All components of the climatic system (atmosphere, hydrosphere, cryosphere, land surface and biosphere) are connected with the water. Extreme anomalies of precipitation in the system atmosphere – land surface and atmosphere – hydrosphere have direct influence on society. These web pages contain information about precipitation anomalies on a daily, monthly and multi-monthly time scale on 22 stations in Croatia.

Monitoring wet and dry conditions on daily time scale is based on the squared root normal distribution. Input data are:

• Daily precipitation data from the long term period: January 1961 – December 2000.
• Daily precipitation data from the previous month.

On the monthly and multi-monthly time scale the statistical model for the analysis of precipitation anomalies is based on the gamma distribution and the standard normal distribution. Input data are:

• Monthly precipitation data from the period: January 1961 - December 2000.
• Monthly precipitation data from the last four years.
