I was recently in Venice and it appears the 'feel temperature' is almost always significantly higher then actual temperature, sometimes by as much as 5c. So the forecast could be 25c and the feel 30c. Why is this? I would have thought the opposite would have been the case as the water would cool the air.
When the sun heats water, water vapor rises into the sky and forms clouds. This is part of a weather cycle that occurs everywhere. Heat from this vapor also can be felt, and is known as humidity. Surprisingly it does not cool, but adds to the temperatures and is warmer than the air as is needed to rise into the clouds. Air conditioners and dehumidifiers can combat this weather behavior.
Ok cheers for the replies. So the basics of this are that water retains heat better than air? But then how does water become hotter than the air that is heating it?
No. Venice is built on water. The humidity is high. In high humidity our heat regulation via sweating is less efficient, therefore we feel hotter.
Okay interesting! But then surely our feel of the temperature would be higher than the actual temperature?
Get yourself a dehumifier if you live there, see if that helps in your home at these times, i.e summer
Heat Index "...combine air temperature and relative humidity to determine the human-perceived equivalent temperature-how hot it feels." http://en.wikipedia.org/wiki/Heat_index
thought meant Venus planet first. read and mean cityin europe! was gone to say closer to sun? readed answers and some would fit for planet too! neet huh?
