dear mrunal sir
firstly i heartly appriciate of your good work on this field . I also thanks to all your team mate who has been working non stop .
Hatsoff mam…keep up good work. .,..many students are benifiting from these lecturers..
I have a doubt regarding tropical easterly jet(TEJ). As explained by Ma’am,its path is from somalia to tibetian plateau. however, in many places, the tropical easterly jet has been named the African Easterly jet and flows parallel to latitutes over northern africa. Moreover, the path as given by rajtanil ma’am does not indicate easterly origin. please clarify!! @mrunal sir, @rajtanil ma’am. @ANYBODY!
