About seasonal distribution of atmospheric precipitation in the south of the Khabarovsk Territory

The analyzed relations between the summer precipitation totals and precipitation totals of the previous winter periods of 1974–2008 based on the data from three weather stations of the Khabarovsk Territory showed that in 80% of cases the low precipitation total of the winter months is followed by a low precipitation total in summer, and, vice versa, in the case of a high (above a multiyear mean) precipitation total in winter, the precipitation total in summer is also above a multiyear mean. There is no relation between the precipitation total in summer and the precipitation total in the subsequent winter periods. It means that the change in the distribution of precipitation between the winter and subsequent summer seasons occurs in the winter months, which must allow forecasting the precipitation total in summer from the precipitation total in the previous winter period, for example, for assessing the fire danger in forests from the weather conditions.
