查询词典 geometric series

By using the multi-year series of the circulation indices P and C for the closed pressure system on the unit radius spherical surface,three characteristic quantities of annual system centers(around the climatological center C-) are defined.1Average distance r,which is defined as the weighted geometric average distance of the annual system centers C deviating from the climatological center C-(i.e.the center location anomaly C′),is a measurement for distribution area of the system...
