Communication report regarding the incidences of drought conditions in Poland

Year: 2010; period: 10 (1.VII - 31.VIII)

In the tenth reporting period, i.e. from 1 July to 31 August 2010, there was no occurrence of agricultural drought conditions in Poland.

This year's July was one of the warmest months of the last century. The highest temperature occurred in Wielkopolska (above 22°C); a slightly lower temperature was in the centre of Poland (21-22°C) and 20°C in the rest of the country. Throughout Poland, the norm for three decades from 1971 to 2000 has been significantly exceeded in Podlasie, Warmia and Mazury, and in Wielkopolska and Lubuskie by more than 4°C. In the rest of country a 3-4°C difference was taken with the lowest above norm (2.5- 3°C) in small coastal areas as well as in the south of the country.

August was also very warm. The highest average temperature (over 20°C) occurred in the Lublin region, while the lowest around 17°C in Przedgórze Sudeckie and Pogórze Zachodniosudeckie.

In July, we found a large variation in precipitation. The highest rainfall exceeding 300 mm occurred in the south and south-east of the country (160-200% of long-term norm). High rainfall also occurred in the Dolny Śląsk and Opole region (120-150 mm, i.e. approximately 150% of norm), and especially in the Kotlina Kłodzka (over 180 mm, i.e. 160-200% of long-term norm), as well as a wide strip (about. 100 km) from Ustka to Torun (120-140 mm, 160-180% of norm). However, in the Warmia and Mazury regions, eastern Mazowsze and northern part of the Lubelski region the precipitation was small (50-70 mm, i.e. 50-80% of long-term norm).

In August, a large variation in the sum of precipitation also took place. High rainfall was recorded in western and north-western parts of Poland and Western Beskidy, locally exceeding 200 mm (significantly higher than the long-term norm). However, reduced precipitation, not exceeding 80 mm (close to normal) occurred on the Silesian Plains and Uplands.

In the sixty-day period, a clear upward trend in the value of CWB continued. Relative to the ninth reporting period, the value of CWB increased on average by about 70 mm, the largest on the coast, Podlasie, Kujawy and Beskidy - by more than 100 mm.

The highest value of CWB, even more than 100 mm occurred in the southern Polish regions, and lowest in central and southern parts of the Mazowieckie voivodeship (-50 ÷ -79 mm) and in the northern Lubelskie voivodeship (-50 ÷ -69 mm).
