`QUALITYHUMANPOWER NEEDED FOR STUD­IES'

Down to Earth - - APPRAISAL -

ter­ac­tion.Next year,we shall un­der­take three ma­jor field ex­per­i­ments in col­lab­o­ra­tion with Bri­tish in­sti­tu­tions to understand the at­mos­phere,aerosols and up­per oceans over the In­dian re­gion. mo­sphere-ocean in­ter­ac­tions, such as sea sur­face tem­per­a­tures,hu­mid­ity,air pres­sure and ra­di­a­tions. We have about 160 sub­mersible floats that are de­ployed un­der wa­ter and track mea­sure­ments on their way back to the sur­face. We also re­ceive data from about 600 sub­mersible floats de­ployed at dif­fer­ent lo­ca­tions around the In­dian Ocean by other coun­tries.We have started in­stalling Au­to­mated Weather Sta­tions (aws) on ships to ob­tain mea­sure­ments, such as at­mo­spheric pres­sure, wind ve­loc­ity, hu­mid­ity, sea sur­face tem­per­a­tures, ra­di­a­tions, from dif­fer­ent di­rec­tions. We have al­ready in­stalled aws on about 20 ships and are in the process of ex­pan­sion. We have signed an mou with the Ship­ping Cor­po­ra­tion of In­dia to in­stall aws on their ships. All th­ese data are cru­cial in run­ning Nu­mer­i­cal Weather Pre­dic­tion mod­els and im­prov­ing their ac­cu­racy.

One of our cur­rent projects is part of an In­doUS col­lab­o­ra­tion to study ocean mix­ing in the Bay of Ben­gal, which is pe­cu­liar in its high fresh­wa­ter con­tent.We are one of sev­eral In­dian and Amer­i­can in­sti­tutes to be in­volved in this project to study airsea in­ter­ac­tions over the Bay of Ben­gal and its im­pact on the In­dian mon­soon. We have 20 per­sons col­lect­ing and as­sim­i­lat­ing data. What is re­quired is not nec­es­sar­ily more cap­i­tal, but qual­ity hu­man­power which is largely lack­ing in cli­mate stud­ies.
