This paper deals with the relief influence on the fields of precipitation and their behavior over land and over sea. We found that the intensity H registered during two months is on one hand higher on the mountainous regions and on the other hand H

Eastern France ; France ; Precipitation ; Rainfall regime ; Rhône ; Saône ; Statistical distribution ; Valley ; Weather type
By classifying the daily precipitations according to the various weather types along the Saône and Rhône's valley, it is possible to follow precisely and understand the evolution of the effects of each type from the north towards the south. - (BJ)

Basse-Normandie ; Climatic data ; Climatic trend ; Climatic variation ; Data processing ; France ; Precipitation ; Time series
Climatic records show fluctuations of precipitations over one hundred years in Normandy. However, development of sites and reconstitution of data bases don't allow to underline objectivly trend over one century. - (BJ)

% of the Congolese territory. The rainy deficit rainfall is approximately 10 % and had been accompanied by seasonal precipitation disorganisation. Increasingly, the great dry season (of June to September) lengthens, what induced the shortening of the first rainy
episode (on the average of October to December) or delays of rain beginning. To the south of Congo, as everywhere elsewhere under humid tropics the agriculture is essentially pluvial and is strongly dependent the seasonal precipitation distribution

The data set of this study is composed by daily precipitation values from 22 stations uniformly distributed within the Greek region ; the time series extend from 1958-2000. The objective is to calculate and to analyse the maximum number of dry
