Communication report regarding the incidences of drought conditions in Poland

Year: 2014; period: 03 (21.IV - 20.VI)

The Institute of Soil Science and Plant Cultivation - State Research Institute in accordance with an Act from the Minister of Agriculture and Rural Development has developed the climatic water balance for all Polish municipalities (3,064 municipalities), and based on the soils categories have identified in those municipalities the current agricultural drought risk for the following crops: winter and spring cereals, corn for grain and silage, sugar beets, potatoes, sugar beets, hops, tobacco, field vegetables, shrubs and fruit trees, strawberries and legumes.

In the third reporting period, i.e. from April 21 to June 20, 2014, IUNG-PIB does not state a risk of agricultural drought in Poland. The values of climatic water balance (CWB), which are the basis to assess the risk of drought in most areas, are negative, but these values for the above-mentioned crops are much higher than the critical value.

The lowest CWB values,  as in the first and second reporting period, occurred in the Żuławy Wiślane lowlands, except that these values were lower than in the previous period by 30 mm, currently quoted values ranged from -130 to -139 mm.

Besides Żuławy, low CWB values occurred in almost entire area of Pobrzeże Gdanskie (with the exception of Elbląg Upland), and were from -120 to -129 mm. For areas with low values of CWB may also be include Starogardzkie and Iławskie Lakeland and Tucholskie Upland and Wysoczyzna Świecka, in these areas CWB values were recorded from -110 to -119 mm.

For the whole country the average CWB value in the current reporting period was lower than the previous period by 24 mm.

The highest CWB values (like ten days ago), were recorded in the Karpaty Foothills, western Beskidy and in the Lublin Upland, except that in the current period were about 20 mm lower than in the previous period and ranged from 60 to 110 mm.

May this year, in terms of thermal conditions was relatively diverse. The highest air temperature occurred in eastern and south- eastern part of Poland, reaching more than 14°C. In most parts of the country temperature of 13 to 14°C were recorded. The coldest was in the north of the country and in the mountains, in these regions the air temperature was 11-12°C. In most parts of the country, the air temperature in May was within the long term norm, only higher than the long-term average by 1°C was recorded in the north of the country.

In the first ten days of June highest air temperature occurred in western Poland, reaching in Ziemia Lubuska and the Śląska Upland highest temperature ranging from 17.5 to 18.5°C. In the large area of Poland, temperature ranged from 16.5 to 17.5°C. In the eastern part of north country, the temperature was lower and ranged from 15.5 to 16.5°C.

The second ten days of June was relatively cold. The warmest areas of the country was the western and south-western parts of Poland with temperatures ranging from 16 to 18°C and the coldest areas of the north-eastern parts of Poland with temperature from 13 to 16°C.

In May precipitation was very diverse. The lowest precipitation occurred in the north and especially in the north-eastern part of the country from 20 to 100 mm, and accounted for 100% of long-term norm. The farther south, the rainfall values were higher, and were exceeding long-term norm  by over 100%. The highest rainfall from 100 to over 300 mm was recorded in the Sudety, Lublin Upland, eastern and western Beskidy, Podhale and Tatry. The long-term norm were exceeded in the western parts of Poland like Malopolska Upland, Podhale, Tatry (over 250%), and in the Lublin region by as much as 350%. In some places, record precipitation was not noted even for decades.

Precipitation in the first ten days of June was very varied, from small, few millimeter in Ziemia Lubuska, Śląska Upland and the Karpaty Foothills and western Beskidy, to 5 to 20 mm occurring over a large area of the country. In the east part of the north parts of the country, precipitation was higher, ranged from 20 to 40 mm and at the edge of the country rainfall amounted to 50 mm.

In the second ten days of June the highest rainfall was recorded in the northern part of the country ranging from 30 to 60 mm, the further south the rainfall was lower and in the Polish Uplands were even less than 5 mm. In southern Poland precipitation was little larger, from 5 to 20 mm.
