On this Teacher’s Day I take the opportunity to convey my wishes to a couple of people who were actively responsible for teaching me a lot of weather concepts during my early days in the Kea Blog. Selvan (Selcyclone) without whom possibly I would have never understood about Cyclogenesis & Steering of cyclones and Pradeep John who possibly has influenced my understanding of weather more than anybody. Last but not the least I would like to recollect my incident with Siva (Novaknole) who explained me about radar & movement of thunderstorms over a cup of coffee when I handed over his first RG made with a Water Bottle. Happy Weather Blogging All.
