A
ir can carry a specific maximum amount of water vapour depending upon its temperature. The warmer the air the moister it can be, if a moisture source is available. The value is approximately 7% more moisture per degree Celsius of added warmth, but the equation works both ways thus: if warm, moist air is progressively cooled it can hold less and less moisture. That is a key factor in why rain happens in the first place. Here's how it works.

When an airmass rises it expands, because the higher it goes above Earth's surface, the lower the atmospheric pressure there is to confine it. As the airmass expands, the gas molecules that make it up move outwards and in doing so they have to push other molecules out of their way. The process uses up energy. Temperature is simply an expression of the energy of the molecules in a system, so if energy is used up then the temperature drops. It's the same reason why highly-pressurised gases being squirted from a spray-can feel cold to the touch: they are rapidly expanding on release from the confining environment of the can, doing work against other molecules in the process and consuming energy.

As the air continues to rise and cool it reaches its dew-point - the temperature at which the air can no longer carry all of the water vapor which is mixed with it. Beyond that point, some of the water vapor condenses out into liquid water. When the air temperature cools to the dew point then clouds (or fog or dew) begin to form, nucleating on tiny airborne particles such as dust or pollen. Further cooling of the air leads to even more water vapor condensing since the dew point continues to fall with the air temperature.

The Northern Hemisphere is warmer than the Southern Hemisphere: i thought the forum had established this!

As for the floods well let's all use words like 'probably' and go back to drinking shall we Roll Eyes

What does a warmer Northern hemisphere have to do with polar deserts?

Can you say positively that the floods would still have occurred and been as extreme if the rivers and drains were cleared?
