Over the northern SCS, analysis results find the lower troposphere is convectively unstable during the entire onset period. The favorable atmospheric conditions for convection are attributed to low-level moisture convergence caused by the frontal southwesterly flow during the first stage, and the retreat of western Pacific subtropical high and warm-moist southwesterly flow from the Bay of Bengal during the later stages.

分析结果显示，在1998年南海夏季季风肇始发展过程中，南海北部的大气大多呈现对流不稳定的形势，第一阶段锋前西南气流造成低层强烈的水气辐合，第二阶段之后锋面远离且太平洋副热带高压东退，来自孟加拉湾的西南气流夹带大量暖湿水气使得南海北部在整个季风肇始期间都是有利於对流的状况。

In this paper the mathematical models and methods for GPS single-point positioning are studied systematically on the theory.All kinds of error correction formulas are studied,such as ironsphere correction,troposphere correction,relativistic effect correction,earth rotation correction ,earth tides correction ,satellites antenna phase center offset correction. GPS single-point positioning programs is coded with pseudoranges and broadcast ephemerides,phases and broadcast ephemerides,and phases and precise ephemerides.And a great amount of computation has been done using the data collected .The results are computed with the 24 hour pseudoranges observation data before and after the canceling of the SA.
