Characteristics of precipitation at the meteorological station Puczniew in 1972-2002

key words: atmospheric precipitation, coefficient of variability, number of days with pre-cipitation, maximum precipitation


The distribution of precipitation is a particularly important factor in periods of critical crop plants which the greatest demand for water. At this work a number of meteorological characteristics associated with precipitation got in Puczniew station in years 1972-2002 were analysed: annual and six-month sums of precipitation; changeability of sums of annual and six-month precipitation (with using the division of years and months on extremely dry, very dry, dry, average, wet, very wet and extremely wet surface); number of days with precipitation (in periods < 10 mm, 10.1 -20 mm, 20,1-30,0,0 mm, 30.1-40.0 mm and above 60.0 mm); appearing of rainless periods. In examined 31-years from1972 to 2002 the averaged annual sum of falls in Puczniew amounted to 540.7 mm. From performed analysis we obtained none of years extremely dry and particularly humid: 2 years stayed ranked to dry, 27 - up to averages, 2 - to humid. Years 1983 and 1989 were dry, however year 1977 was humid and 2001 very humid. On average within one year it appeared about 3 rainless periods, appearing mostlyin summer year (59% of cases), and dominating droughts have lengths from 9 up to 17 days (90%).
