daily precipitation data from aphrodite's resources with a spatial resolution of 0.25*0.25 degree for 57 years have been used to detect the trend of precipitation in afghanistan. first of all, monthly, seasonally, and yearly maps and regional mean time series calculated. according to the annual map, mean annual precipitation of the country is about 256 mm. there are two precipitation maxim...

Prototype coarse-grained stochastic parametrizations for the interaction with unresolved features of tropical convection are developed here. These coarse-grained stochastic parametrizations involve systematically derived birth/death processes with low computational overhead that allow for direct interaction of the coarse-grained dynamical variables with the smaller-scale unresolved fluctuations...

Pp. 47?. Philadelphia: Lea Brothers & Co. 1897. This book is intended for the use of three classes of persons: " the present generation of physicians who prescribe travel, the travelers themselves, and the rising generation of medical students should be taught to recognize the principles of medical climatology and its proper relation to general therapeutics." The author rightly summarises much ...

The present state of a system can be described as a linear function of the state at the previous time, plus timeindependent noise. data assimilation: Method of optimally combining irregularly spaced observations with dynamical constraints to produce dynamically consistent fields on regular grids.
