Utilizing the data of NWP products in Europe center and Japan facsimile charts of 9～11 from 1996 to 1998, we develop the forecasting system of heavy precipitation over Luohe according to different weather patterns.
Based on analysis of a large region pr ecipitation in kelamayi from 7to 8Oc tober of 2002,it were described that the characteristics of circulation background,physical quantities,and s atellite images when the heavy precipitation was formed in the kelamayi area,and the physical quantities products of T 213 were tested.
It was shown that the first strong precipitation phase was affected by typhoon itself and for the second precipitation process, the major casue was the result of interaction between the typhoon circulatin and minlatitude systems.
Using the 6 stations precipitation data in the Sanxia area and weather chart data from October to January during 1961—1994,the prior indexes of regional severe precipitation in Sanxia area are analysed under 500hPa circulation of “big U”pattern.
The severe precipitation process occurred over Yunnan at 08:00 from 5 to 6 January 2003 was simulated using the mesoscale numerical model MM5.The results of analysis indicate that the southwest lower-level jet(LLJ) is the main synoptic system which resulted in the heavy rain.
The OSL ages along with other Thermoluminescence (TL) and Radiocarbon (14C) ages support the conclusion that the Baota landslide was originally triggered by strong precipitation occurred in a warm climate period of 30,000-40,000?years?BP.
Present strong precipitation hardened aluminum alloys do not have high endurance limits.
It was shown that this type of processing develops maximum reduction in size of the chromium dendrite phase without breakage and that the deformation produces a strong precipitation of the chromium from solid solution.
Although system L2 is simulated, the strong precipitation coverage is less conspicuous.
During the period of strong precipitation the stream rose in two hours from 1 l/s to 50 l/s.
SGI did not undergo thiol oxidation at 60°C, but at 80°C SGI underwent severe precipitation and thiol oxidation, which caused the enzyme to deactivate.
The results showed that exposure at 600°C for 80 hours or longer caused severe precipitation of chromium carbides along the grain boundaries characterizing the sensitization of the material despite it being titanium stabilized.
This may be ruined by more intense events such as larger local earthquake or severe precipitation.
