AB  - This paper describes the frequency analysis of absolute maximum air temperatures, using annual maximum series (AMS) in the period 1961–2010 from 40 climatological stations in Serbia with maximum likelihood estimation of distribution parameters. For the goodness of fit testing of General Extreme Value (GEV), Normal, Log-Normal, Pearson 3 (three parameters), and Log-Pearson 3 distribution, three different tests were used (Kolmogorov-Smirnov, Anderson-Darling, chi-square). Based on the results of these tests (best average rank of certain distribution), the appropriate distribution is selected. GEV distribution proved to be the most appropriate one in most cases. The probability of exceedance of absolute maximum air temperatures on 1%, 0.5%, 0.2%, and 0.1% levels are calculated. A spatial analysis of the observed and modeled values of absolute maximum air temperatures in Serbia is given. The absolute maximum air temperature of 44.9 °C was recorded at Smederevska Palanka station, and the lowest value of maximum air temperature 35.8 °C was recorded at Zlatibor station, one of the stations with the highest altitude. The modeled absolute maximum air temperatures are the highest at Zaječar station with 44.5 °C, 45.6 °C, 47.0 °C, and 48.0 °C and the lowest values are calculated for Sjenica station with 35.5 °C, 35.8 °C, 36.1 °C, and 36.2 °C for the return periods of 100, 200, 500, and 1000 years, respectively. Our findings indicate the possible occurrence of much higher absolute maximum air temperatures in the future than the ones recorded on almost all of the analyzed stations.

AB  - This research is devoted to the determination of hidden dependencies between the flow of particles that come from the Sun and precipitation-induced floods in the United Kingdom (UK). The analysis covers 20 flood events during the period from October 2001 to December 2019. The parameters of solar activity were used as model input data, while precipitations data in the period 10 days before and during each flood event were used as model output. The time lag of 0–9 days was taken into account in the research. Correlation analysis was conducted to determine the degree of randomness for the time series of input and output parameters. For establishing a potential causative link, machine learning classification predictive modeling was applied. Two approaches, the decision tree, and the random forest were used. We analyzed the accuracy of classification models forecast from 0 to 9 days in advance. It was found that the most important factors for flood forecasting are proton density with a time lag of 9, differential proton flux in the range of 310–580 keV, and ion temperature. Research in this paper has shown that the decision tree model is more accurate and adequate in predicting the appearance of precipitation-induced floods up to 9 days ahead with an accuracy of 91%. The results of this study confirmed that by increasing technical capabilities, using improved machine learning techniques and large data sets, it is possible to improve the understanding of the physical link between the solar wind and tropospheric weather and help improve severe weather forecasting.

AB  - The impact of solar activity on environmental processes is difficult to understand and complex for empirical modeling. This study aimed to establish forecast models of the meteorological conditions in the forest fire areas based on the solar activity parameters applying the neural networks approach. During July and August 2018, severe forest fires simultaneously occurred in the State of California (USA), Portugal, and Greece. Air temperature and humidity data together with solar parameters (integral flux of solar protons, differential electron flux and proton flux, solar wind plasma parameters, and solar radio flux at 10.7 cm data) were used in long short-term memory (LSTM) recurrent neural network ensembles. It is found that solar activity mostly affects the humidity for two stations in California and Portugal (an increase in the integral flux of solar protons of > 30 MeV by 10% increases the humidity by 3.25%, 1.65%, and 1.57%, respectively). Furthermore, an increase in air temperature of 10% increases the humidity by 2.55%, 2.01%, and 0.26%, respectively. It is shown that temperature is less sensitive to changes in solar parameters but depends on previous conditions (previous increase of 10% increases the current temperature by 0.75%, 0.34%, and 0.33%, respectively). Humidity in Greece is mostly impacted by solar flux F10.7 cm and previous values of humidity. An increase in these factors by 10% will lead to a decrease in the humidity of 3.89% or an increase of 1.31%, while air temperature mostly depends on ion temperature. If this factor increases by 10%, it will lead to air temperature rising by 0.42%.

The criteria of the Koppen climate classification are presented, on the basis of which the climate regionalization of Serbia has been carried out. The methodology of making maps of air temperatures and precipitation amounts has been described, on the basis of which a map of the climate regions of Serbia has been created.

It has been pointed to the constraints of the climate regionalization that arise from the theoretical bases of the climate classifications, but also from nature of the collected data and the applied methodology.

AB  - There was a stagnation in temperature rise in the period 1998-2012, despite increase in greenhouse gases radiation forcing (hiatus period). According to Global Circulation Models simulations, expected response on the rise of greenhouse gases forcing is tropical temperature altitude amplification temperature increases faster in higher troposphere than in lower troposphere. In this paper, two satellite data sets University of Alabama in Huntsville, Microvawe Sounding Units (UAH MSU) and Remote Sensing Systems (RSS), were used to test altitude temperature amplification in tropics in the hiatus period. We compared satellite data sets both for the temperature of the lower troposphere and the temperature of the middle troposphere, in general and particularly for land and ocean (for UAHMSU). The results from both satellite measurements showed the presence of hiatus, i.e. slow-own of the temperature rise in the period 1998-2012 compared to period 1979-2012 (UAHMSU) and temperature fall for RSS. Smaller increase, i.e. temperature fall over ocean showed that hiatus is an ocean phenomenon above all. Data from UAH MSU showed that temperature altitude amplification in tropics was not present either for period 1979-2012, or 1998-2012. RSS data set also does not show temperature altitude amplification for these periods. RSS data for successive 15-year periods from 1979-1993 till 1998-2012 does not show tropical temperature altitude amplification and in one case negative trend is registered in lower troposphere and in two cases in middle troposphere. In general, our results do not show presence of temperature altitude amplification in tropics in the hiatus period.

AB  - The temperature of charged particles coming from the Sun ranges from several hundred thousands to several millions °C, in extreme cases. Theoretical possibilities of the hydrodynamic air mass seizing by charged particles, i. e. solar wind, are discussed in this paper. On one hand, they are characterized by extremely high temperatures, on the other, by the compression of cold air at an approximate altitude of 90 km towards the top of the cloud of the cyclone, they influence the phenomenon of extremely low temperatures. By using the Mann-Whitney U test we have tried to determine the potential link between certain indicators of solar activity and resulting disturbances in the atmosphere. Analyzed data refer to global daily values for the 2004-2010 period. Our results confirm the possibility of coupling between the charged particles and the vortex air mass movements, based on which a more detailed study of the appearance of a tornado near Sombor on May 12th, 2010, was carried out. It has also been proven that there are grounds for a causality between the sudden arrival of the solar wind charged particles, i. e. protons, and the appearance of a tornado. Based on the presented approach, elements for an entirely novel prediction model are given.
AB  - Temperature visokoenergetskih čestica koje dospevaju sa Sunca kreću se u opsegu od nekoliko stotina do nekoliko miliona stepeni celzijusa. U ovom radu razmatrana je teorijska mogućnost hidrodinamičkog zahvatanja vazdušnih masa sunčevim vetrom (SV), odnosno visokoenergetskim česticama SV. Na jednoj strani, ove čestice karakterišu ekstremno visoke temperature, a na drugoj, one izazivaju kompresiju veoma hladnog vazduha sa visine od oko 90 km ka vrhu ciklona. Upotrebom Man-Vitnijevog U testa, pokušali smo da detektujemo povezanost između određenih pokazatelja sunčeve aktivnosti i poremećaja u atmosferi (korišćeni dnevni podaci na globalnom nivou za period 2004-2010). Dobijeni rezultati potvrđuju mogućnost veze između visokoenergetskih čestica SV i vrtložnog kretanja vazdušnih masa, zbog čega je urađena detaljnija analiza slučaja pojave tornada (trombe) kod Sombora 12. marta 2010. godine.

AB  - The connection between the solar flux at 2.8 GHz (based on mean monthly values) and the outbreaks of gypsy moths (Lymantria dispar L.) in Serbia was investigated. The researches included six outbreaks from 1952 to 2007. The average values of the solar flux ranged between 83.8 and 101.8 sfu during the outbreaks, whereas they were between 147.9 and 188.3 sfu for the periods without outbreaks. The results of the research showed that the increase in the number of gypsy moths appears when the values of the solar flux at 2.8 GHz range from 70 to 120 sfu.

AB  - The paper deals with temperature and precipitation trends in the period 1949 -2006 recorded in the network of 18 meteorological stations in Serbia. The second half of the 20th century is particularly interesting for this type of research, because in this period, according to statements of the Intergovernmental Panel on Climate Change (IPCC), anthropogenic influence has a dominant role in climate oscillations. This influence is reflected in the increase in global temperature, while in our region it should be noted first of all as decrease of precipitation quantity. For detecting and evaluation of trends Mann-Kendall test was used. Due to poor sensitivity to individual errors and outlayers (i.e. rare, atypical extreme values), for evaluation of the trend movement Senn's method was chosen. At annual level, in several stations (Belgrade, Negotin, Zaječar, Palić, Sombor, Prizren, Zlatibor, Sjenica), statistically significant upward air temperature trend has been noted. At the level of the whole Serbian territory upward air temperature trend is present, although without statistical significance (z=1,44). Similar results have been obtained by the analysis of absolutely maximum air temperatures. Only in Vranje, Smederevska Palanka and Sombor statistically significant upward trend is present; when absolutely minimum temperatures are in question neither upward nor downward trends have been detected in any of the stations. When precipitation is in question (at annual level) insignificant positive trend (z=0,64) has been noted for Serbia on the whole. Negotinska Krajina shows significant negative trend, while the extreme south regions, i.e. south west regions of Serbia (Zlatibor, Sjenica, Prizren) demonstrate statistically significant positive trend. According to this, temperature changes in Serbia in the second half of the 20th century demonstrate to be in compliance with the global change, although they are statistically insignificant. Changes in total precipitation quantities do not justify the hypothesis on dominance of the anthropogenic greenhouse effect. Annual draught index according to Em. de Marton records irrelevant changes, on the basis of which a conclusion could be drawn that in Serbia on the whole there has been no change in landscape type in the monitored period. In order to examine characteristics of the monitored climatic elements their seasonal values have been analyzed as well. .

Druga polovina dvadesetog veka je posebno interesantna za ovu vrstu istraživanja jer u njoj po tvrdnjama Međuvladinog panela za klimatske promene (IPCC) u klimatskim kolebanjima dominira antropogeni uticaj.

Zbog slabe osetljivosti na pojedinačne greške i autlejere (tj. retke, atipično ekstremne vrednosti), za ocenu nagiba trenda je odabran Senov pristup. Na godišnjem nivou, na nekoliko stanica (Beograd, Negotin, Zaječar, Palić, Sombor, Prizren, Zlatibor, Sjenica) je uočen statistički značajan uzlazni trend temperature vazduha. Na nivou cele Srbije, postoji uzlazni trend temperature vazduha, ali bez statističke značajnosti (z=1,44). Slični rezultati se dobijaju i pri analizi apsolutno maksimalnih temperatura vazduha.

Negotinska krajina pokazuje značajan negativan trend, dok krajnji jug, odnosno jugozapad Srbije (Zlatibor, Sjenica, Prizren) pokazuju statistički značajan pozitivan trend. Dakle, promene temperature u Srbiji u drugoj polovini HH veka su po znaku u skladu sa globalnim promenama, ali nisu statistički značajne.

AB  - In the presented paper correlation between the northern part of the Atlantic ocean (belt between 50-65°N) and the atmospheric pressure is examined. Connection between the ocean temperature and atmospheric pressure is the most obvious in the El Nino southern oscillation mechanism. Thus, so far it is not known that such a mechanism exist in the Atlantic ocean. The main accent in the presented paper is focused on the connection between Iceland low and the sea surface temperature (SST) in the subpolar part of the Atlantic ocean (used data are in grid 5x5°). By hierarchical cluster analysis five relatively unified clusters of sea surface temperatures grid cells are defined. By multiple linear regression, we examined the correlation between each of the depicted clusters with position and intensity of Iceland low, and identified the most important grid cells inside every cluster. The analysis of the relation between Iceland low and air temperature in Serbia and Belgrade has shown the strongest correlation for the longitude of this centre of action. .
AB  - U radu je ispitivana veza između temperature vode severnog dela Atlantskog okeana (pojas od 50-65°N) i atmosferskog pritiska. Povezanost okeana i atmosfere se najočiglednije manifestuje u mehanizmu El Ninjo južne oscilacije. Međutim, koliko je poznato, u Atlantskom okeanu ne postoji ekvivalent El Ninja, niti ovako jasno izražena povezanost između temperature okeana i atmosfere. Težište istraživanja je stavljeno na ispitivanje povezanosti Islandskog minimuma sa promenama temperature vode u subpolarnom pojasu Atlantika (datim u mreži 5x5°). Hijerarhijskom klasterskom analizom je izdvojeno pet relativno ujednačenih klastera temperature vode subpolarnog dela Atlantskog okeana. Njihova povezanost sa položajem i intenzitetom Islandskog minimuma ispitana je višestrukom linearnom regresijom. Ustanovljeno je koji od klastera najviše utiče na geografsku širinu, geografsku dužinu i intenzitet Islandskog minimuma i koja od gridnih ćelija u okviru svakog od klastera predstavlja najznačajnije prediktore. Ispitivanjem odnosa između položaja i intenziteta Islandskog minimuma sa temperaturom vazduha u Srbiji i Beogradu, ustanovljeno je da je najsnažnija povezanost sa geografskom dužinom ovog akcionog centra. .

abstract = "In the presented paper correlation between the northern part of the Atlantic ocean (belt between 50-65°N) and the atmospheric pressure is examined. Connection between the ocean temperature and atmospheric pressure is the most obvious in the El Nino southern oscillation mechanism. Thus, so far it is not known that such a mechanism exist in the Atlantic ocean. The main accent in the presented paper is focused on the connection between Iceland low and the sea surface temperature (SST) in the subpolar part of the Atlantic ocean (used data are in grid 5x5°). By hierarchical cluster analysis five relatively unified clusters of sea surface temperatures grid cells are defined. By multiple linear regression, we examined the correlation between each of the depicted clusters with position and intensity of Iceland low, and identified the most important grid cells inside every cluster. The analysis of the relation between Iceland low and air temperature in Serbia and Belgrade has shown the strongest correlation for the longitude of this centre of action. ., U radu je ispitivana veza između temperature vode severnog dela Atlantskog okeana (pojas od 50-65°N) i atmosferskog pritiska. Povezanost okeana i atmosfere se najočiglednije manifestuje u mehanizmu El Ninjo južne oscilacije. Međutim, koliko je poznato, u Atlantskom okeanu ne postoji ekvivalent El Ninja, niti ovako jasno izražena povezanost između temperature okeana i atmosfere. Težište istraživanja je stavljeno na ispitivanje povezanosti Islandskog minimuma sa promenama temperature vode u subpolarnom pojasu Atlantika (datim u mreži 5x5°). Hijerarhijskom klasterskom analizom je izdvojeno pet relativno ujednačenih klastera temperature vode subpolarnog dela Atlantskog okeana. Njihova povezanost sa položajem i intenzitetom Islandskog minimuma ispitana je višestrukom linearnom regresijom. Ustanovljeno je koji od klastera najviše utiče na geografsku širinu, geografsku dužinu i intenzitet Islandskog minimuma i koja od gridnih ćelija u okviru svakog od klastera predstavlja najznačajnije prediktore. Ispitivanjem odnosa između položaja i intenziteta Islandskog minimuma sa temperaturom vazduha u Srbiji i Beogradu, ustanovljeno je da je najsnažnija povezanost sa geografskom dužinom ovog akcionog centra. .",

AB  - In the distinctive mountsinod area of the Mt. Stara Planina, mesoclimate zoning was performed with certain generalization level in climate zone separation. Furthermore, due to lack of available data base, the aforementioned altitude zoning must not be considered strictly within presented altitude volumes. Outstanding terrain dissection, different level of vegetation covering and enhanced impact of secondary, i.e. tertiary climate modificators in certain parts of the Mt. Stara Planina, may create microclimate or topoclimate conditions which essentially differ from the present quantitative values of climatic elements in sub-mountainous, mountainous or high-mountainous areas. This fact is particularly apparent if we have in mind that the climate is one of the essential factors for creation of the relief periglacial forms; their inventory and systematization as well as complex population analysis could indirectly offer data on climate conditions in huge areas which are not covered by meteorological monitoring. However, quantification of climate elements in this region is a methodological problem which requires qualitatively different access and a different data base. Substantial lack of appropriate climatologic data has been substituted by particularly detailed study on vegetation of this mountain area with data on climatogene communities and communities for which there are good climatic indicators (particularly communities with detailed measurements in other mountainous areas); as far as the areas above the upper forest limit are concerned, detailed research has been performed regarding the recent periglacial processes and their relief forms as direct climatic-geomorphologic indicators of the high mountains (periglacial) climate. We believe that this attempt of climate zoning of the Mt. Stara Planina, as distinctive mountainous area, by comparison of detailed vegetation and periglacial-geomorphologic research as well as research of the upper forest limit, is the only proper way of performing this task due to lack of instrumental measurements at high altitudes. .

Dobijena klimatska rejonizacija koja se u uslovima Stare planine svodi na visinsku pojasnost jasno pokazuje direktnu uslovljenost klime, savremenog stanja u rasporedu vegetacije i savremenih periglacijalnih geomorfoloških procesa iznad gornje šumske granice. .
