These waters are the origin of tropical cyclones that move to Asia and Thailand. Compared with other neighboring countries in South East Asia, Thailand is relatively less impacted by these cyclones, with an average of two to three cyclones per year. It is potential that the number of tropical cyclones moving to Thailand is gradually decreasing. Tropical cyclones usually take place from the months of May to December, and most frequently from Sep- tember to November. A cyclone that moves to Thailand may decrease its severity and become a depression that brings more rain to certain areas of the country. Without a cyclone, droughts are imminent. However, if a cyclone increases its severity and becomes a tropical storm or typhoon, natural disasters such as storms, floods, storm surges, and landslides are likely to happen causing damages to life, properties, and agricultural areas of inhabitants. Therefore, when a warning is issued regarding the formation of tropical cyclones around the waters surrounding the country and the possibility that these cyclones will move to Thailand, it is recommended that Thai people follow weather forecasts and be prepared for natural disasters in order to mitigate the loss of life and properties. Key words : tropical cyclone, tropical depression, tropical storm, typhoon ¿“§ºπ«° µ“√“ß∑’Ë Ò √“¬™◊Ë Õ擬ÿ ∑’Ë °à Õµ— «∑“ß¡À“ ¡ÿ ∑√·ª´‘ øî °¥â “πµ–«— πµ°·≈–∑–‡≈®’ π„µâ ª√–‡∑»∑’Ë µ—È ß™◊Ë Õ Column 1 Column 2 Column 3 Column 4 Column 5 °— ¡æŸ ™“ DAMREY ¥Õ¡‡√¬ KONG-REY °Õ߇√¬ NAKRI π“°√’ KROVANH °√Õ«“≠ SARIKA “√‘ °“ ®’ π LONGWANG YUTU ¬Ÿà ∑Ÿà FENGSHEN ø߇©‘ π DUJUAN µŸâ ‡®’È ¬π HAIMA ‰ÀÀ¡à “ À≈ßÀ«“ß ‡°“À≈’ ‡Àπ◊ Õ KIROGI ‰§‚√®‘ TORAJI ‚∑√“®‘ KALMAEGI §— ≈‡¡®‘ MAEMI ‡¡¡‘ MEARI ¡‘ Õ–√‘ Œà Õß°ß KAI-TAK ‰§µ—Í ° MAN-YI ¡“πÀ¬’Ë FUNG-WONG CHOI-WAN MA-ON À¡“ßâ Õπ øÕß«Õß ©Õ¬À«—Ë π ≠’Ë ªÿÉ π TEMBIN ‡∑¡∫‘ ß USAGI Õÿ ´“ß‘ KAMMURI §— ¡¡ÿ √‘ KOPPU §Õ∫ªÿ TOKAGE ‚∑–§“‡ß– ≈“« BOLAVEN ‚∫≈“‡«π PABUK ª“∫÷ ° PHANFONE æ— πΩπ KITSANA °‘ π“ NOCK-TEN 𰇵π (ª≈“∫÷ °) (°ƒ…≥“) (π°°√–‡µÁ π) ¡“‡°ä “ CHANCHU ®— π®Ÿ WUTIP À«Ÿà µ‘Í ∫ VONGFONG PARMA ªÑ “À¡à “ MUIFA À¡ÿà ¬øÑ “ À«à Õßøß
