Abstract: | By the utilization of monthly precipitation data from all stations in the Northern Hemisphere annexed to the “World Survey
of climatology, Vol. 1–15”, the distributions of the maximum precipitation months (MPM), the annual relative precipitation
(ARP) and the monthly relative precipitation (percent of annual) in January and July are respectively mapped. Moreover the
distributions of intermonthly relative precipitation variabilities from January to December are plotted as well. From these
figures, the precipitation in the Northern Hemisphere may be classified into three types(continental, oceanic and transitional
types) and 17 regions. The precipitation regime may also be divided into two patterns, the global and regional patterns. The
global pattern consists of planetary front system and ITCZ and its inter-monthly variation shows the north-and-south shift
of the rain belt; the regional pattern consists of the sea-land monsoon and plateau monsoon regime, in which the inter-monthly
variation of rain belt shows a east-and-west shift. |
