Isotherms and isohumes in Pune on clear winter nights: A mesometeorological study

Abstract

Results of   two temperature mobile surveys conducted during clear, calm winter nights at Pune are presented. Warm pockets existed wherever agglomeration of buildings existed. Twin heat islands are noticed in Pune on either side of the river. Isohumes followed the same pattern of isotherms except vice versa in magnitudes. Isohumes and isotherms exhibited double peaks-one, four hours after sunset and another at the minimum temperature epoch.
