The trends in occurrence frequencies of circulation types over Europe and in nine climate variables in the Czech Republic conditioned by the types are examined for period . The circulation types are determined by an objective procedure from daily 500 hPa heights. Both in summer and winter, anticyclonic types have become more frequent at the expense of cyclonic types. The circulation changes are shown to be unrelated to the trends in surface climate elements in summer, whereas in winter, trends in circulation explain a part of the observed warming and strengthening of southerly winds.The trends in climate elements are not uniform among circulation types. In summer, the trend pattern consisting of decreasing maximum and daily mean temperatures, daily temperature range (DTR) and sunshine duration, and increasing cloudiness and relative humidity is observed under the cyclonic types and the types with a well-pronounced jet, but is missing under types with a blocking anticyclone over Europe. Two possible mechanisms causing this trend pattern are proposed: increasing cloudiness, and a process responsible for the reduction of sunshine without a concurrent increase of cloudiness. The latter mechanism can possibly be identified with increasing aerosol concentrations. In winter, the degree of warming is governed by changes in zonal wind. The mechanism of change in DTR seems to vary with elevation: at the lowland station (Prague-Klementinum), the increase in DTR is related to the warming trend, and consequently with zonal wind changes, while at the mountain station (Milešovka), the increase in DTR reflects the increase in precipitating clouds.The changes in DTR are related much more to mid-tropospheric circulation than to cloud cover in summer, whereas in winter, cloud cover plays a more important role in affecting DTR trends.

“…At the same time, this study shows that the growth trend of T min is larger than the growth trend of T max , which also coincides with data, presented in numerous studies that analysed extreme air temperatures (Brázdil et al 1995;Tuomenvirta et al 2000;Türkeş et al 2002;Lazić et al 2006;Savić 2009). Some contemporary studies have demonstrated a connection between atmospheric circulation represented by the Hess-Brezowsky classification and changes of climatic elements in Europe (James 2007;Jones and Lister 2009;Cahynová and Huth 2009;van den Besselaar et al 2010;Hoy et al 2013aHoy et al , 2014.…”

“…The analysis of the annual T max and T min trends in the Autonomous Province of Vojvodina (Serbia) shows a statistically significant increasing trend in the second half of the twentieth century and at the beginning of the twenty-first century, which generally coincides with the results of other researchers who have investigated the region of Europe (Brázdil et al 1995;Brunetti et al 2000;Tomozeiu et al 2002;Türkeş et al 2002;Yan et al 2002;Founda et al 2004;del Río et al 2007;Savić 2009). At the same time, this study shows that the growth trend of T min is larger than the growth trend of T max , which also coincides with data, presented in numerous studies that analysed extreme air temperatures (Brázdil et al 1995;Tuomenvirta et al 2000;Türkeş et al 2002;Lazić et al 2006;Savić 2009).…”

This paper presents an analysis of the homogenised mean maximum (T max ) and minimum (T min ) temperatures. The data used in the analysis were collected at eight stations in the Autonomous Province of Vojvodina (Serbia) during the 1949-2008 period. The trends obtained from the slopes of the regression lines using the least square method show 0.9°C/ 60 years for T max and 1.1°C/60 years for T min ; the nonparametric Mann-Kendall test was used to determine the statistically significant increasing trends of these two extreme parameters. In this paper, we analyse the influence of the Vangengeim-Girs classification of atmospheric circulation on the T max and T min trends in the Autonomous Province of Vojvodina (Serbia) using linear and quadratic models based on the least square method. Linear stepwise regression and the forward method reveal the highest dependence of T max and T min when the W or E circulation types are included in the model. Non-linear models show a greater contribution of T max and T min at W, E and C circulation types, respectively. The correction of the variance contribution of quadratic models ranges from approximately 16 to 44 % for T max and 32 to 38 % for T min .

“…Dans les Alpes Suisses, Beniston et al [10] et Beniston et Rebetez [9] ont montré que la température minimale annuelle avait augmenté de 2 o C sur la période 1901-1992 et que la durée d'ensoleillement avait diminué depuis les années 1980. Des tendances similaires ont été observées en République Tchèque [17] et en Autriche [32] pour les périodes 1961-1992 et 1961-1990. En France, une étude récente menée sur 82 stations de plaine (71 stations ont une altitude inférieure à 400 m) a permis de mettre en évidence une forte augmentation de la température minimale depuis 1965, notamment en été (+0,93 o C) et en automne (+0,88 o C) (période 1910-1986) [22]. Pour la température maximale, les auteurs ont observé, après une période de diminution (-0,62 o C ; 1910 à 1965), une augmentation sensible surtout en été (+0,86 o C ; .…”
