Abstract:
The evolutionary features of the whole tropospheric precipitable water, the intensity of vertical ascending motion in the lower layers over Hangzhou, and the surface precipitation in Hangzhou are analyzed by the NCEP/NCAR reanalysis grid data of humidity and vertical velocity, as well as the stationary data of precipitation in Hangzhou, from January 1951 to November 2003. The results show that there is significant interannual variation both in precipitable water and vertical ascending motion, and even though both precipitable water and vertical ascending motion are favorable, the precipitation would not certainly greater than normal, which means that atmospheric water resources have great potential. The longterm variation features of atmospheric precipitable water in June over Hangzhou are compared with those of other places at the same latitude over the world, and the results show that the precipitable water in the troposphere in June over Hangzhou and the other cities at the same latitude had a decreasing trend in the past 53 years.
