Globally, the most pronounced diurnal precipitation amplitudes have been recorded in summer (Dai 2001).
Kikuchi & Wang (2008) have identified three tropical diurnal precipitation cycle regimes using the satellite data--oceanic, continental and coastal.
A pronounced late afternoon to early evening precipitation maximum was revealed in the interior regions of India and South Africa (Sen Roy & Balling 2007; Rouault et al.
Comparison of maximum observed precipitation of synoptic stations of Semnan province with each other also show that maximum observed precipitation in Shahrod city is more than other cities and in Semnan is more than Garmsar and Damghan.

In the current study we consider precipitation data obtained from 40 meteorological, hydrological, and precipitation monitoring stations owned by the Estonian Meteorological and Hydrological Institute, the locations of which are shown in Fig.
Before carrying out the analysis of the time series, we first obtained the 15-and 30-day sums of the precipitation data.
Long-term trends (1945-2010) of the weights of seasonal precipitation within the annual values reveal that, during the cold semester, the weight has a slightly decreasing trend, while in the warm semester, the weight of precipitation amounts within annual values shows a slightly increasing trend (Fig.
As in the case of long-term evolution trend (1945-2010) of the atmospheric precipitation (Fig.
Traditional analysis of the precipitation regime is carried out on the basis of the precipitation sums in a day, a 10-day period, a month and a year, and also on the number of dry and wet days in a month and a year, on the maximum number of consecutive dry and wet days, extremes with fixed thresholds, precipitation percentiles, etc.
Here are some examples of the indicators of the extreme precipitation regime (R is total precipation in a day):
