    Based on consideration of the difference of climatic precipitation probability and orographic influence over river valley, a new calculation method of area rainfall suit to hilly land river valleys is proposed according to the Gauss weight interpolation.The advantage/disadvantage of the new method and Taisen polygon method are discussed. At the same time,the relationship between area rainfall and flood is studied as well.

    Based on the differences of their synoptic situation, physical elements field, etc. two typhoon processes which affect South China 2—8 July, 2001, as an example, are discussed. The results show that the main reasons of differences from strength to falling areas of heavy rainfall in the two processes are follows: typhoon Durian interacted with westerly system in mid latitude, at the same time, moisture flux convergence dilated above 500hPa. On the contrary, typhoon Utor turns weakening after landing and it is only a isolated tropical weather system because of the obstruction of subtropical high pressure, and moisture flux convergence is located below 850hPa. Moreover, the wet potential vorticity(MPV) has better relation with heavy rainfall.

    连志鸾 王丽荣
    2003, 29(10):17-21. DOI: 10.7519/j.issn.1000-0526.2003.10.004
    [Abstract](603) [HTML](0) [PDF 402.19 K](714)
    Based on data of air temperature, humidity, wind, cloud at eleven weather stations from 1955 to 2002 in Shijiazhuang, high temperature events are investigated. The synoptic and climatic characteristics of high temperature events are analyzed. Prediction equation and quantitative forecast flow are developed, and the high temperatures (≥40℃) can be more successfully forecasted.
    5  Study of Climatic Factors and Prediction of Spring Dust Storms in Central-Western Inner Mongolia
    李海英 高涛 薄玉华
    2003, 29(10):22-25. DOI: 10.7519/j.issn.1000-0526.2003.10.005
    [Abstract](525) [HTML](0) [PDF 328.95 K](642)
    The large scale spring dust storms (March—May) in central western Inner Mongolia are analyzed statistically by using meteorological data of 1961—2000. Based on the climatic features of precipitation, the whole region is divided into several parts in order to find the relationship between dust storms and rainfall. The results show that more dust storms are companied with less precipitation and more cold wave in springs. The subtropical high, the zonal circulation index of Asia, the 500hPa height of the Qinghai Xizang Plateau, Southern Oscillation, atmosphere circulation patterns of Atlantic Ocean Europe have some influence on dust storms.
    6  Maintenance and Fault Diagnosis of CINRAD/SA Radar
    胡东明 伍志方
    2003, 29(10):26-28. DOI: 10.7519/j.issn.1000-0526.2003.10.006
    [Abstract](1074) [HTML](0) [PDF 225.28 K](721)
    There are perfect auto calibration and auto fault diagnosis systems in the CINRAD/SA radar system. General maintenance could be carried out by means of “alarm message” and “RDA performance and maintenance data”. Referring to “adaptation data”, the failure would be isolated and localized with simple instrumentation.
    7  Analysis of Two Continuous Low Temperature Events from 2002 to 2003
    张小霞 付湘宁
    2003, 29(10):29-32. DOI: 10.7519/j.issn.1000-0526.2003.10.007
    [Abstract](550) [HTML](0) [PDF 381.57 K](562)
    From last dekad of December 2002 to first dekad of January 2003, two cool injury appeared successively in Guangdong Province. With the new analytic system (MICAPS2 0), an analysis of the two events is made from the circulation situation, gradient of physical quantity and atmosphere stratification etc., and the results show that the contributing factors and “cold rain” effect are different for the two events.
    8  Analysis of a Meso-scale Heavy Rain Event in Eastern Shandong Peninsula
    崔晶 张丰启
    2003, 29(10):33-37. DOI: 10.7519/j.issn.1000-0526.2003.10.008
    [Abstract](751) [HTML](0) [PDF 1.79 M](602)
    A meso-scale heavy rain occurred in Shongdong Weihai city during June 24 to 25, 2002 is analyzed with synoptic map, the satellite image, HLAFS data and Shuman Shapiro meso scale filter. The result shows that under the background of interaction between high-level westerly trough and southwest flow on the western border of Western Pacific subtropical high, the event was mainly caused by meso-scale cyclone in the uscending area.
    9  Analysis of Severe Convection Process in Weifang, Shandong Province
    鲁丹 王令军 崔建云
    2003, 29(10):38-41. DOI: 10.7519/j.issn.1000-0526.2003.10.009
    [Abstract](431) [HTML](0) [PDF 362.94 K](569)
    Based on the data from Qihe Doppler radar, Weifang radar and automatic meteorological stations, an analysis of severe convection event in Weifang, Shandon Province on May 19,2003 is made. The results show that the eastwards quick moving transversal trough and its train cold wave strengthened the instability, while, low-layer warm and wet current provided dynamical and water vapor condition for its development.
    10  An Analysis of the Relationship between SARS and Meteorological Conditions in Beijing Area
    叶殿秀 杨贤为 张强
    2003, 29(10):42-45. DOI: 10.7519/j.issn.1000-0526.2003.10.010
    [Abstract](451) [HTML](0) [PDF 267.04 K](588)
    Based on the series of daily SARS incident numbers from April 21 to May 20,2003,in Beijing area, the vacillating measurements affected by meteorological condition are separated from total tendency, with orthogonal polynomial methods. The results of correlation analysis show that they are significantly related with daily maximum temperature, daily range and relative humidity ahead of 8 to 9 days. On this basis, the regression estimation model can perfectly fit historic series of daily incidence fluctuation of this disease.
    11  Impacts of Cool Injury in Winter on Banana Yields in Guangdong Province
    刘玲 高素华 黄增明
    2003, 29(10):46-50. DOI: 10.7519/j.issn.1000-0526.2003.10.011

    Though abundant climate resources are favor to the development of banana production, banana suffers magnitude lose for cool injury, even in southwest where is the warmest area in Guangdong. The effect of cool injury on banana are analyzed. The cool injury, which severely impact on banana growth, happened every 5 years normally in Guangdong, but cool injury comes frequently during the 90's of last century. Because of more economic benefit, the plant area of counter season banana expands quickly, and the bud bursting or differentiation is in winter, the potential fatalness of meeting cool injury is increased, and resulted in more impact on banana yield. So the banana planting should be think much of cool injury, wind damage and risk of market, and the situation of site and time in Guangdong, and do well on avoid and mitigation disaster.

    [Abstract](395) [HTML](0) [PDF 212.51 K](529)
    The favourate date for Raising Seedling and transplanting of Hybrid Rice is analyzed. It is showed that the temperature of start seeding date is above 86℃ of five day sequence mean temperature in the third dekad of March and is above 80℃ in the first dekad of April.The temperature of start transplanting date is that of the assurance rate is above 80% of mean daily temperature steadily passing through 16℃ with the consideration of high product rice age and the factor of secure blooming. It is ultimately determineded according to local weather forcasting,rice growing and the former crops harvesting.
