The thermal effects of bodies of water
Bodies of water regulate temperature because they
store heat during the day and then slowly release that heat during these cool
fall evenings.
Water serves to regulate the temperature of the surrounding areas. The high heat
capacity of the Atlantic Ocean, for example, serves to keep New England warmer
than one might think for a place so far north (e.g. Montana).
In these two images, you can see the effects of smaller bodies of water (lakes
and rivers). In the visible image, the lakes are seen in the early morning
(around 8am). In the thermal image, the lakes are visible as being warmer than
the surrounding land of the cool countryside.
