Abstract:
Studying on the relationship between the variation of chlorophyll-a (Chl-a) contents and monsoon wind system in the Indian ocean using Chl-a concentration maps (of marine living organisms), detected by Sea-viewing Wide Field-of-view Sensor (SeaWiFS) instruments, and the average monsoon wind per month during year 2001 from QuikSCAT/SeaWind as a case study. It was found that monsoon wind system affecting on Chl-a contents of marine living organisms which can be used as a criteria index tool to exhibit the potentiality of these organisms as the primary producers in food chain. Wind in Northeast monsoon season during October-March, and Southwest monsoon season over May-September are related to Chl-a blooming that in the northern Indian ocean, Chl-a concentration in Southwest monsoon season was higher than those in Northeast monsoon season. Whereas in the southern Indian ocean, Chl a concentration was high in Northeast monsoon season. In addition, the Inter Tropical Convergence Zone (ITCZ) pattern was studied. It was found that it shift up to the land during June-August in the southwest monsoon season, and then shift back to the ocean in September.
