A Study on Practical Objective Forecast Method of Flying Hazardous Weather：Thunderstorm

Lin Tse-Ming

Abstract

　　Thunderstorm and rainshowers occurred due to thermal and terrain effects in the period from June through September, are two of the most dangerous hazards for aircraft flight. Based on the rawinsonde observation data taken from 1971 to 1974 at Taoyuan, Makung, and Tungkong, and the surface observation data taken in the same period at Sungshan, Taoyuan, Hsinchu, Chin Chuan Kung, Chiayi, Tainan, and Pingtung S.B., and by use of the statistical and weather analysis methods, the objective forecast diagrams for each of the above mentioned seven surface stations have been obtained. By use of these diagrams, the probabilities of occurrence and nonoccurrance of thunderstorm and rainshower can be predicted more accurately. Thus, the flying safety of both military and civil aircrafts can be also insured.
