ผลกระทบของปรากฏการณ์เอ็นโซ ต่อปริมาณฝน อุณหภูมิ และความถี่พายุหมุนเขตร้อนบริเวณพื้นที่ชายฝั่งประเทศไทย / ภูเวียง ประคำมินทร์ = Impacts of ENSO on rainfall, temperature and tropical cyclone frequency in coastal areas of Thailand / Phuwieng Prakhammintara
The data of rainfall, annual average air temperature and numbers of tropical cyclone in the year 1951-1998 from 26 meteorological stations in the coastal areas of southern and eastern parts of Thailand were analyzed by using regression analysis and difference of means methods. The results of regression analysis were as follows: air temperature was changed in the southeastern coastal area, no change in the amount of rainfall and the frequency of tropical cyclone. In addition, the results of difference of means method were as follows: no significant difference between Southern Oscillation Index (SOI) and coastal temperature, neither between SOI and amount of rainfall, for 96% of the stations. The average correlation of annual amount of rainfall and Monsoon Index was 75.2% for the stations in coastal areas of Thailand. The correlation were 71.4% for Bangkok and east coast stations, 83% for southern east coast stations, 71.4% for southern west coast stations. When EI Nino occurred, temperature was significant higher than average value of 30 years, however amount of rainfall and numbers of tropical cyclone were lower than the average
