This was the first case in the second half of the twentieth century of an EHS in a small western part of the area (7 stations, Fig. 2). During the entire summer, the average temperature exceeded the long-term average by 2.0–2.7 °C, but the greatest difference was in Krakow. August was particularly hot and in this month, the coverage of the hot area extended beyond the EHS area into the east and south. In these areas, this was the hottest August of the study period. In Krakow, where the summer of 1992 was the only EHS during the study period, the temperature difference in August reached 4.3 °C (t ? t av + 3?).
It second speculation are substantiated of the a record lot from days that have a max temperatures exceeding 35 °C (thirteen compared to the mediocre of 0.cuatro, while in Warszawa it was step 3 as compared to average away from 0.2). In the a south area of the area affected there are more than ten days that have the very least temperature greater than 20 °C (Desk six). At the time, Central European countries is dominated by a long-term circulation regarding southwest (Kossowska-Cezak 1993) connected with an anticyclonic wedge regarding the Azores within this and therefore good supplementary high-pressure system developed over the Balkans. It beautiful Wroclaw women pressure shipment trend triggered a keen advection out of exotic sky. Although this feeling put up, a beneficial foehn snap lead to heat escalation in southern area Poland (Kuziemska 1987). Temperatures swells were plus observed in Main Europe various other decades within the equivalent weather conditions (Fink ainsi que al. 2004).
Really the only individual day you to definitely reached one to classification are August in the Riga. The typical temperature of summer exceeded the fresh new enough time-term average by dos.1–dos.4 °C. An average limitation heat is actually instance highest (the best throughout the data several months), during the northern channels you will find and lots of weeks that have a maximum temperatures greater than twenty five °C (30–forty days compared to the twelve–17 weeks on average, Table 6).
This new EHS off 1998 covered simply a tiny southeastern part out-of the space, including three station (Ural’sk, Orenburg and you will Aktobe). The essential difference between an average temperatures of EHS and the long-name average ranged regarding dos.nine to three.2 °C. June stood out using its higher temperatures, even in the event most of the months had temperatures higher than new a lot of time-title average. It very hot June, the latest from the data months, are seen from Samara to your Caspian Water plus it stood aside with a really high volume of the preferred months, i.e., with an optimum temperatures over thirty-five °C and you can the absolute minimum temperature significantly more than 20 °C, which is fourfold more this new much time-identity mediocre (Table 6).
The EHS covered a vast area of western Russia, Belarus and the Ukraine (with an extremely hot June), but the seasonal average temperature only met the criterion at three stations located far apart from each other (Riga, Minsk and Chisinau), where the temperature difference compared to the long-term average was 2.2–2.9 °C (Table 6). Three other stations, i.e., St. Petersburg, Smolensk and Odessa, fell marginally short (by just 0.1 °C), of meeting the criterion t ? t av + 2?.
This summer feel appeared many days with an excellent restrict temperatures more than 25 °C (33–fifty, as compared to mediocre out of twelve–24) and you can significantly more than 30 °C (6–9 against. 2).
