ปัจจัยทางอุตุนิยมวิทยาที่มีผลต่อความเข้มข้นของคลอโรฟิลล์เอบริเวณอ่าวไทยจากการศึกษาด้วยเทคนิครีโมทเซนซิ่ง / วรรณรัตน์ ภูมิวงศ์พิทักษ์ = Meteorogical factors associated with chlorophyll-a concentration in the Gulf of Thailand as studied by remote sensing technique / Wannarat Phoomwongpitak
The pattern of the chlorophyll a distribution in the Gulf of Thailand that found during 1998-2000 from SeaWiFS imagery data, described here are similar to those of previous in situ studies. In the upper part of the Gulf, high chlorophyll a concentration was detected every month espeacially in rainy season at the main four river mouths. However, high chlorophyll a concentration did not occur in the middle and the lower of the Gulf despite of the nutrient from the inshore discharging into the coastal sea. In winter seasons, chlorophyll a concentration was the higher than in summer and rainy seasons. Possible causes for this include variation in monsoon and meteorological factors. According to the statistical analysis, sunshine duration and air temperature play a major role affecting chlorophyll a concentration in all seasons. While in rainy season, rainfall duration is an important factor in chlorophyll a concentration. It was found that declined light,elevated air temperature and amount of rainfall were induced high chlorophyll a concentration. In addition, in summer and winter seasons, air temperature and light was a major and minor important factors affecting in chlorophyll a concentration, respectively.
