Temperature distribution over Bombay during a cold night

Abstract

A mobile temperature survey of Bombay and Greater Bombay was conducted in the early hours of 11 January 1975. The survey shows a 'heat Island' over the Malabar Hill, Girgaum and Cuffee Parade area with a maximum temperature difference of about 11° between the urban and the almost rural suburbs. The horizontal temperature distribution is found to be influenced by proximity to the sea, concentration of population, tall buildings and industry and the prevailing wind field. Vertical temperature profile measurements over the Worli Television tower indicate the top of presumably the first inversion layer in this area to be around 127 m on this day.
