Is there a relationship between rainfall and temperature??

Question

Can you explain how this relationship works and why this is so?

Answer 1

There is a loose relationship and in general higher termperatures are assocaited with higher rainfall.

When it's hot more water is evapourated from the seas and oceans, this is the starting point of rain. The hotter it is the more evapouration and the more moisture in the air.

But... the warmer the air is the more water vapour it can contain, problems start to occur when the air cools down, this happens when the warm air rises and also when it mixes with colder air. As it cools it can contain less water vapour, when it gets to the point that it can't contain any more water vapour (saturation point) the vapour condenses into water droplets which subsequently fall as precipitation - rain if it's warm, snow if it's cold.

To complicate things: almost all evapouration occurs from the seas and oceans and as the wet air mass moves inland it tends to deposit rain, especially if it meets high ground and the air is forced upwards. Coastal and hilly areas tend to attract more rain.#

If you're a long way inland or if you're in an area where wind rarely delivers water laden air masses then rainfall is going to be significantly lower - whatever the temperature.

There's much more to it than that but hopefully this gives you an idea. Sorry if it's not explained very well - I hope it makes sense.

Answer 2

An agent called moisture is required to trigger the rainfall.Over the desert where no moisture is available, increase of temperature will not produce any rain.On the other hand ,in other places where enough moisture is available in the atmosphere,heated air parcels rise due to bouyancy and cools at a particular height resulting in the codensation of air producing rainfall.So , if air temperature is brought down to the dew point temperature, there is always a possibility of rainfall.More temperature can hold more moisture and therby produce more rains.

Answer 3

Yes, higher temperature usually goes with increased rainfall. Higher temperature means a higher absolute humidity (mass of water/volume of dry air), so when it rains, there is a lot of water available in the air to become rain.

Answer 4

While it is true that warm air CAN hold a lot of moisture, it doesn't necessarily hold it (think of a subtropical desert in summertime). You need warmth, humidity and condensation to produce maximum rainfall. If the first two are present, condensation naturally occurs through convection and cooling.

Answer 5

Normally the temperature is higher when it rains than it would have been if it didn't. It just feels colder because any wind removing moisture from your skin will give you a sort of "natural air conditioning."

Answer 6

Frankly saying both rainfall and temperature are couples.
They are husband and wife. If one is getting angry means (i.e) if man gets angry means the girl start crying. This is the logic.

Answer 7

When water vapor is lowered enough, it condensates ( turns into liquid water - RAIN). When rain gets heated enough it becomes water vapor.
