Most of these selected regions have unfavorable hydro-meteorological conditions for agricultural. This activity is carried out using a nationwide system of automatic meteorological stations. ASSESMENT OF PRECIPITATION CONDITIONS IN POLAND IN JUNE 2013 USING SPI Indicators important for agriculture: soil moisture index SMI, agricultural drought index CDI, potential reduction of crop yield, are calculated using other agro-meteorological factors (air temperature, wind speed, vapor pressure, sunshine duration or radiation, evapotranspiration). The present results of monitoring and forecasts of all indices in the form of maps and tables are shown on-line at the site: www.agrometeo.itep.edu.pl . The standardized precipitation index SPI is used for monitoring and forecasting precipitation deficits and surpluses. The SPI is calculated for each month at the 1-, 2-, 3-, 6-, 12-, 24-, 36- and 48- month time scale. SPI–1, SPI–2 - shorter time scale indexes describe drought events affecting agriculture (soil moisture depleting, crop yield reduction), SPI–3, SPI–6 is used for seasonal drought identification SPI–12, SPI–24, SPI–48 - for a long-term drought identification, suitable for water resources hazard (reservoirs storage, stream flows, groundwater levels) Extreme drought Severe drought Moderate drought Mild drought Normal Wet Moderately wet Very wet Extremely wet ● meteorological stations FORECAST OF PRECIPITATION CONDITIONS USING SPI DESCRIPTION OF MONITORING SYSTEM STANDARDIZED PRECIPITATION INDEX SPI agrometeo.itep.edu.pl. * Project is financed by Polish Ministry of Agriculture and Rural Development Programme: Monitoring, Predicting of Progress and Risk of Water Deficit and Surplus in the Rural Areas, 2011 – 2015. ** Bogdan Bak, PhD – poster presenter, meteorologist and agrometeorologist superviser collecting meteorological data and preparing meteorological forecast on the basis of MeteoGroup Poland and WetterOnline models REFERENCES McKee T.B., Doesken N.J., Kleist J.
