Averaged precipitation
Predicted and climatological averages of precipitation show their probability rather than the actual daily precipitation quantity. Significant deviations between graphs mean drier or wetter periods expected
Probabilyty of significant precipitation
Here is a forecasted probability of precipitation more than 1 mm. It shows the general distribution of rainy weather in time. Some periods may contain more or less rainy days
For now, these are preliminary data that still need to be refined.
The distribution of precipitation is highly dependent on local conditions and topography. Precipitation can be caused by both local and global processes in the atmosphere. The last ones, such as monsoons and westerlies, are more likely to be successfully predicted in a long range. Therefore, if your region is under their influence, you are more lucky.
