Abstract
The paper is a follow up to the study on air temperature conditions at Easter from the year 2009. Easter precipitation amounts and depth of new snow, maximum depth of new snow and total snow cover in the period 1961-2010 in CR are analyzed.
The influence of time variability of Easter and variability of atmospheric circulation on behaviour of precipitation characteristics under the study are assessed. Five-day precipitation totals have almost no dependency on calendar shift of tracked part of the year (determination 0,1 per cent) while total snow cover depth sinks with very high determination of 98 per cent.
Depth of new snow sinks with determination of 55 per cent. When evaluating precipitation conditions extraordinariness it has to be distinguished between deviation from long-term calendar interval or just among Easter.
But there is considerable influence of Easter-calendar shift hidden in the second case, especially for snow characteristics. This influence is 12 per cent for maximum of total snow cover depth and only about 2 per cent for precipitation amount and for new snow characteristics.
Absolute maxima of daily precipitation amounts, new snow and total snow cover at selected stations in CR for the whole period of measuring at these stations are given.
