rainfall precipitation
2.The results showed that the main meteorological factors to influence the yield of Summer millet inthis county were insufficient total—precipitation and the irrational distributionof the rainfall,especially the lack of precipitation during the first ten—day pe-riod of September.
3.The precipitation frequencies is analysed according to 1956~2000 years of rainfall record series in Baoding area. The features of distribution of rainfall are detailed evaluated. Firstly,the distribution of monthly precipitation is not even.
4.RAINFALL FEATURES OF THE TIBETAN PLATEAU AND LFO INFLUENCE ON LOW FREQUENCY PRECIPITATION IN THE YANGTZE RIVER BASIN
5.More analysis indicates that SST and 500hpa field, 500hpa field and precipitation of China have distinct correlation, and it can explain the relation between SST and China rainfall: winter SSTA can be transferred by circulation and influence precipitation of east China, in particular, the transition of SST in 1976, make the circulation and rainfall change.
6.Suqian has the monsoon climate of warm temperate zone, with abundant sunshine and rainfall. Its annual temperate averages 14℃ and the annual average precipitation is 913 mm.
7.Based on the collected data of mud rock flow in combination with rainfall condition, the author puts forward the early warning precipitation and range for slope mud rock flow, slide mud rock flow and gully mud rock flow and countermeasures.
8.According to two kind of rainfalls sensor structures and the principles of AWS,different titration time of the standard ball simulative precipitation are promoted, and the field calibration rainfall sensor method has been discussed from controling adjustment precipitation intensity, recording calibration firsthand information detailedly,pay attention to the problems occurred in the field calibration and so on.
9.The analyses suggest that the first and second categories of rainstorms are associated commonly with the strong inertial instability in the upper troposphere, as well as respectively with symmetry and convective instabilities, and their rainfall is large; and the third and fourth categories generally produce stable precipitation with a small rainfall, and their upper tropospheres are usually inertially stable.
10.Rainfall-runoff simulation files were made by using data such as precipitation and ET observed in 2004 and 2005 and the DEM, landuse in 2002. The spatial grid of all the DEMs were 10m×10m, 30m×30m, and 50m×50m, the step of the temporal data were 5 or10 minutes, 1 or 2 hours.
