latitude effect
1.The results indicated that the LRGR mean winter rainfall longitudinally distributed along river, while the unique topography of LRGR did not obviously have impact on the winter rainfall; the winter temperature distribution was like belt, which decreased from low latitude to high latitude; the passing-obstructing effect of LRGR cannot be clearly showed with the winter temperature distribution; but such effect is obvious over Nu-valley and Lancang-valley.

3.LATITUDINAL EFFECT OF MAGNETIC STORM ON APRIL 6,2000 AT LOW-LATITUDE MERIDIAN CHAIN
5.In the higher- latitude zones (40°S- 70°S,40°N- 70°N),the sea levels in both the northern - western andsouthern - western Pacific areas are being the obvious risings and their rates in the higher latitude zones are 1. 5 mm/yr and 2. 5 mm/yr, respectively, it is confirmed that the effect ofice - sheet melting in the Antarctica on the sea level change is stronger than that in theGreenland.
6.Based on GIS technique and geographic correction model with 5 environmental factors of longitude,latitude,height above the level,grade and slope of terrain, drought spatial distribution with relative high resolution of 1 km was made from scatter data of DDI of 86 stations,which could reflect the effect of terrain factors to drought distribution with more detail.
