    Typhoon is the most intensive synoptic system that can result in heavy rainfall in China. The interaction between the westerly trough and synoptic system far from typhoon constantly leads to abrupt reinforcement of rainfall and severe disaster.The north part heavy rainfall is called as heavy rainfall far from typhoon. Researches show that heavy rainfall far from typhoon mostly occurred at the right side behind the south-westerly high-Jet that has distinct non-zonal features, at the same time, reinforcement of heavy rainfall is closely associated with strength of non-zonal features. Researches on heavy rainfall far from typhoon and non-zonal high level Jet streak are reviewed.

    By using conventional observation data, HLAFS grid data and GMS cloud data, physical mechanism affecting weather system and rain-formation, interaction and inter impact between low and middle latitude weather system are analyzed and diagnosed. The results indicate that several strong rain procedures occur in the large-scale background of middle-high latitude in Eurasia. The low-eddy which forms in the east area of Qingzang plateau and develops in the Sichuan Basin and its shear line are the main weather systems. The rain intensification is closely related with interaction between middle and low latitude systems, specific construction of plateau eddys.

    4  On Snowstorm Disaster and Its Formation Process in Inner Mongolia
    宫德吉 李彰俊
    2001, 27(8):19-23. DOI: 10.7519/j.issn.1000-0526.2001.8.004
    [Abstract](660) [HTML](0) [PDF 469.21 K](775)
    Firstly,the circulation evolution features of snowstorm in Inner Mongolia in last 50 years is analysed.It is pointed out that barber,heavy snow and severe detemperature do together damage to human and animals more seriously in company with freezing disaster.They are the main factors of disaster formation.Strong jet,stronger frontal zone and strong divergence in upper air along the coast of north China become beneficial factors of vapor travelling from south to north.These factors promoted the formation of snowstorm in Inner Mongolia.Lastly,several circulation features of snowstorms in Inner Mongolia are analysed.
    5  Influence of the Winter Snow Cover in Tibetan Plateau and Eurasia on Summer Rainfall in China
    孙林海 宋文玲
    2001, 27(8):24-27. DOI: 10.7519/j.issn.1000-0526.2001.8.005
    [Abstract](732) [HTML](0) [PDF 355.33 K](751)
    According to the relationship between the snow cover in Tibetan Plateau and Eurasia in winter and the summer rainfall in China, the correlation between the summer rainfall in China and the snow cover in Plateau and Eurasia is verified. Results indicate that the prediction of summer rainfall is better by snow cover over the Plateau than that over Eurasia. The flood of the Changjiang River valley in summer usually occurred when anomalous snow cover in Tibetan Plateau is above normal in winter. This is an important indicator for the prediction of rainfall in summer.
    6  Application of the Mesoscale Numerical Model (MM5V3) in Shenyang Regional Meteorological Center
    周小珊 杨森 张立祥
    2001, 27(8):28-32. DOI: 10.7519/j.issn.1000-0526.2001.8.006
    [Abstract](728) [HTML](0) [PDF 323.82 K](662)
    The mesoscale numerical model (MM5V3) was used on the personal computer in Shenyang Regional Meteorological Center. There are some differences between MM5V3 and MM5V2 when MM5V3 was compiled by Fortran 90 in its pre process and post process. The longitudinal and latitudinal grid data set of the initial field and the boundary was created by T106L19 and sounding data set. The outputs of prediction were joined with plotting systems of Vis5d and Grads. The results of MM5V3 are better than those of MM5V2 which had been used in 2000 flood season, but not all.
