Climate is one of the most important factors that enable the existence of life on Earth. The climate has been studied by many scientists throughout the history for its influence on all living and non-living beings. Researchers have used climatological parameters (temperature, humidity, rainfall, sunshine duration, evapotranspiration etc.) with different approaches and created a variety of methods. When putting these classifications into consideration, they have taken different criteria into account and have produced different classification. Some of these formulas are short and simple, some are very long and complex. Using these formulas, researchers have determined different climatic types suited to different regions. In this study, two separate climate classification methods were used (Erinç and De Martonne). Meteorological data ranging from 1980 to 2011 were examined periodically and arranged according to determined classification methods. The data were processed in accordance wi...

En estudios referentes a fenómenos meteorológicos asociados a una región, la Climatología Sinóptica permite analizar las interacciones existentes entre la circulación atmosférica y las condiciones presentes en superficie.El área de estudio de este trabajo se ubica en el departamento Rosario, provincia de Santa Fe donde se realizó una clasificación de los procesos sinópticos asociados a eventos de deficiencias hídricas severas (DHS) que afectan al rendimiento (R) durante el período crítico (PC) del cultivo de maíz.Las condiciones predominantes de los patrones de circulación relacionados con estas masas de aire (ma) evidencian una fuerte subsidencia (descenso de aire) sobre el centro norte del país que impide el ascenso de las ma. También se observa advección (movimiento horizontal) de aire cálido desde el norte y noroeste. El comportamiento de las ma y de sus campos de circulación, asociadas a casos de DHS, presenta un alcance regional en la merma de los R de maíz, ya que su influenc...

Ab s t r a c t. The paper analyses directions of advection of air masses responsible for extreme rain-fall totals resulting in floods in Racibórz and Dobczyce in July 1997 and May 2010, respectively. The analysis was based on the HYSPLIT model available via the READY website of National Oceanic and Atmospheric Administration Air Resources Laboratory (NOAA ARL USA). The database used by the model (NCEP/NCAR reanalysis) contains global grid-based meteorological data updated every 3 hours. The ARL trajectories were used to compute archive trajectories, at 6-h intervals, of two cases of intensive rainfall. The first involved air masses advecting over Racibórz (50.1oN; 18.2oE) from 00.00 UTC 5 July 1997 through 06.00 UTC 9 July 1997, and of air massed advecting over Dobczyce (49.9oN; 20.1oE) from

Although Turkey is situated in large Mediterranean geographical location where climatic conditions are quite temperate, diverse nature of the landscape, and the existence in particular of the mountains that run parallel to the coasts, result in significant differences in climatic conditions from one region to the other. While the coastal areas enjoy milder climates, the inland Anatolian plateau experiences extremes of hot summers and cold winters with limited rainfall (Sensoy et al, 2008).
Turkey receives most of the rainfall in the winter season. In this season, mean temperature usually is below 5°C and there is no too much evaporation. But summer rainfall is very limited and could not be enough to remove water deficit resulted from increased temperature and evaporation. Turkey's diverse regions have different climates because of irregular topography. Taurus Mountains are close to the coast and rain clouds cannot penetrate to the interior part of the country. Rain clouds drop most of their water on the coastal area. As rain clouds pass over the mountains and reach central Anatolia they have no significant capability to produce of rain. In the Eastern region of Anatolia, the elevation of mountains exceeds 2500-3000 m. Northern Black Sea Mountains and Caucasian Mountain hold the rain clouds, and therefore the area is affected by the continental climate with long and very cold winter. Minimum temperatures of -30°C to -38°C are observed in the mountainous areas in the east, and snow may lie on the ground 120 days of the year. Winters are bitterly cold with frequent, heavy snowfall. Villages in thee region remain isolated for several days during winter storms.

The aim of the study is to characterize the frequency and determinants of the synoptic con- ditions of advection of arctic and tropical air masses over the Lublin region. Their occurrence in the regional scale in the years 1951–2010 was based on lower synoptic maps for 12 UTC, which derived from PIHM/IMGW-PIB. In turn, the calendar of circulation types for the Lublin region was used to assess the synoptic conditions of the analyzed air masses. The annual frequency of arctic air masses reached 13.4%. The highest frequency of these air masses occurred in spring, with the maximum in April (20.4%), and the lowest in summer (July and August, < 5%). Days with tropical air were recorded less frequently (4.1% of all days in the year). It is most often found in the summer (with a maximum of 9.2% in July) and the lowest in winter (< 1%). In the years 1951–2010, there were signiﬁ cant changes in the frequency of advection of arctic and tropical air masses (average increase by 8 and 3 days per 10 years, respectively). The occurrence of arctic masses signiﬁ cantly increased in winter, autumn and spring, and tropical in the summer. In all seasons, the arctic air was most likely to be recorded during the northern and northeastern circula- tion types, while the lowest in the southern and southwestern types. In the case of tropical air, it is most likely to occur during air ﬂ ow from directions E-SE-S-SW. Regardless of the time of the year, arctic and tropic air masses are characterized by signiﬁ cant anomalies in air temperature at 850 hPa and 850–1000 hPa thickness.

The aim of the study is to characterize the frequency and determinants of the synoptic conditions of advection of polar air masses over the Lublin region. Their occurrence in the regional scale in the years 1951-2010 based on lower synoptic maps for 12 UTC, which derived from PIHM/ IMGW-PIB. The annual frequency of polar air masses (maritime fresh-mPf, martime old-mPo, maritime warm-mPw and continental-cP) reached 82.5%. The highest frequency of these air masses refers to Polar maritime old air (mPo), with a frequency exceeding 37% (the maximum in summer and the minimum in spring). In the years 1951-2010, there were signifi cant changes in the frequency of advection of CP air (average decrease by 11 days per 10 years), mPf (decrease by 7 days per 10 years), and mPw (increase by 11 days per 10 years). In all seasons, mPo was most likely to be recorded from western direction, mPw from western and southwestern directions, mPf from western and northwestern directions, while CP air from eastern and southeastern directions.

Due to its mechanism and effects, climatic events have been significant facts for humanbeings all times. In this study,the interrelation between the extreme climatic events in Antakya, air masses and, their routes was examined. Using the data related with extreme climatic events received from Turkish State Meteorological Service (TSMS) and NOAA HYSPLIT model (Hybrid Single-Particle Lagrangian Integrated Trajecto-ry), it was aimed to determine the relation between air masses their routes, and the extreme climatic events in Antakya. The routes of air masses that generate the extreme climatic conditions in 96 hours back trajectory plane at 500, 1500 and 3000m heights, according to HYSPLIT model, are given to enable the comparison in terms of altitude and event. During the analysis carried out for various climatic parameters, it was determined that Siberian and Azore anticyclone played an active role for maximum and minimum temperatures, maximum precipitation, and highest snow thickness and during fastest wind periods. The field of study was influenced by the continental polar air mass during the periods of heavy colds in particular, when Azore dynamic cyclone was dominant the highest pluvial period as a flood disaster has been occurred. Furthermore, it was understood that extreme climatic conditions, in particular maximum precipitation periods resulted in severe material damages in the territory.
