And even Puneet reported in Dombivli it was cold in morning. So Kalyan - Dombivli 14 C likely.

Fog is a common affair during winter in upper latitudes. <br />When fog is thick and light rays can not penetrate it the insolation i.e in coming solar radiation is prevented and the earth is NOT getting heated. But losses energy out going long wave radiation relatively more. The pinge of cold will be felt in day time too.Here too the diurnal variation in temp will be less. [Max-min]<br />Similarly when the diurnal variation is large then also the cold bite will be felt. That will occur only in clear skies.

Only 1.5c....unfortunately, I read all the answers in fb, and no one took this hint. ! <br /><br />Now, as we know, open spaces around the city are always cooler, due to less urbanisation.<br />n fact, I have noticed recently, Sjung remains cooler than Palam, a phenomena unheard of say 7years ago.<br />So, proportionately, the outer areas are cooler even in foggy conditions.<br />Rajeshhttps://www.blogger.com/profile/08511057956916968156noreply@blogger.comtag:blogger.com,1999:blog-31136724.post-89357365562721011552012-12-26T21:28:59.244+05:302012-12-26T21:28:59.244+05:30Please read the above city as Purnea in Bihar...Please read the above city as Purnea in Bihar...Arpit Sharmahttps://www.blogger.com/profile/18394747592886798574noreply@blogger.comtag:blogger.com,1999:blog-31136724.post-881424605920018542012-12-26T19:18:19.542+05:302012-12-26T19:18:19.542+05:30Purulia in Bihar is consistently recording below 1...Purulia in Bihar is consistently recording below 15c from the past 10 days...Arpit Sharmahttps://www.blogger.com/profile/18394747592886798574noreply@blogger.com
