    In the World Meteorological Day (WMD), a topic is chosen by WMO every year since 1961 for the public in the world to enhance the understanding of the importance of the meteorological problem concerned. The topic in 2004 is: Weather, water and climate in the information age so as to improve the people's knowledge about the role of water in the sustainable development, the relationship between water, weather and climate, the effect of information transportation in the information age.

    The convetive cloud system on 20 July 2003 in Wuhan region is simulated with a 3-D convective precipitating cloud model. The microphysical characteristics of a mature convective system derived from 3-D cloud model approach to the results from TRMM TMI and PR products. The result from the cloud model is then used as input into a 3-D microwave radiative transfer model that calculates the upwelling radiance received by the rediometer aboard the satellite. The result shows that the structure of cloud has a strong influence on the upwelling microwave radiation.

    A sustained anomalous heavy rainfall event occurred over southern Hubei Province during 20—22 July 1998. A two-way nested nonhydrostatic mesoscale numerical model called MM5 was conducted to simulate the event. The simulative results show that the rain-band distribution with its center is basically consistent with that of the observation, especially for the results derived from the fine nested simulation that are very closely with the observations. In addition, the mesoscale system connecting with the heavy rainfall occurred in 20—22 July is simulated successfully.

    In nourish period, lychee needs warm and wet weather, but in bud differentiation period, lychee needs moderate low temperature and drought. Based on the statistic analysis of the lychee yield and climate data in the last 50 years of 20 century, the key stage and temperature index in the lychee bud differentiation is determined. The key stage in the central part of Guangdong province for middle and latter maturity varieties is from the 2nd dekad of December to the 2nd dekad of January (about in the stage of anthotaxy anlage differentiation). The average temperature in four dekads of the key period is from 11 to 14℃, favor to bud differentiation, the rate of high yield year is about 70%. In a year with the average temperature from 15 to 17℃ for the key period is not favor to bud differentiation, the rate of lean year is about 75%. If in the partial warm year, before the 2nd dekad of January appears the moderate low temperature process, the average temperature in 2 dekads is lower than 15℃, so lychee can also have a better harvest.
    5  Application Study on Satellite-RS-based Drought Monitoring in Fujian Province

    Based on vegetation water supply indexes, RS monitoring patterns and technique are studied in the geographic ecological environment in Fujian Province. Appropriate drought scale indicators are set up, according to the satellite RS dynamic monitoring is conducted on the lasting drought in the winter-spring period between 2001 and 2002 in Fujian Province. The result shows that the monitoring findings accord with the practical situation.

    A process of heavy rain occurred in Shanghai on 5 and 6 August, 2001, the daily rainfall in the Huangpu and Xujiahui broke the record of last 50 years. Based on the densified satellite images, data of Doppler radar from Nanhui, Shanghai, the densified observation, and a dynamic diagnostic analysis of the event is documented. The result shows that it was the development of meso β-scale system that caused the heavy rain. And the deep humid neutral stratification and the symmetric instability, which act as the activator in the development of meso β

    MM5 model system is one of the most widely used mesoscale meteorological modeling system in the world. Due to its nonhydrostatically dynamical structure, optional physical options and the advanced Four-Dimensional Data Assimilation (FDDA), MM5 is mainly used in meteorological research and operational weather predicting domain. For some technical reason, MM5 is always running on UNIX system, the case running on Windows is quite few. Application of MM5 to Windows has been tried and is successful, and an operational weather forecast system is established based on the work. Some problems were put forward, the structure of PC operational weather forecast system and its scheme was introduced.
