Hong kong, with its high population density, torrential rainfall, and dynamic natural terrain, has had its fair share of landslides. today the number of landslide - related fatalities is low, compared to 30 years ago, but there are still around 300 landslide reports every year on average
一九九七年是香港有紀錄以來最多降雨量的一年，天文臺錄得降雨量達三千三百四十三毫米，亦發出六次紅雨和兩次黑雨警告。 -
Using the daily rainfall data of 740 stations over china and ncep daily up - ai data from 1971 to 2000, we analyzed the average mei - yu climate field. based on the climate field and mei - yu intensity index, we confirm that the year of 1999 is a typical mei - yu. besides, the intensity of mei - yu rainfall in 1999 is the highest since we had record, so the analysis of mei - yu in 1999 can present the common characteristics of mei - yu
本文利用1971 - 2000年中國740站的日平均降水資料和ncep的日平均高空資料分析了梅雨氣候場，利用梅雨的氣候場及中國氣象局氣候診斷預測室的梅雨強度綜合指數，確定了1999年是一個非常典型的梅雨年，並且1999年梅雨期間的降水強度是歷史以來的最高值，因此我們對1999年梅雨進行的分析有很大的代表性。 -
Whether in the aspect of total rain days or total rainfall amount in a year, ya ' an is always an extreme range, which has been called " ya - an - tian - lou " in chinese. the predicted average physical structures in the raining process are as follows : ( l ) positive vortex and convergent center in the lower and middle troposphere and negative vortex and divergent center in upper troposphere ; ( 2 ) the superposition of the low layer zonal - vertical circulation and the up layer zonal - vertical circulation forms a strong upward current
從6種不同方案對暴雨過程預報的實驗看，不同的邊界層參數化方案對雨帶特徵的模擬都具有一定的能力，同時模式模擬的降水對參數化方案的選取是敏感的，不同的參數化方案模擬出的降水范圍和雨量分佈有所差異，主要表現在降雨量中心強度及雨區分佈上。
