Untrue, the warmer the climate becomes the LESS unstable the weather becomes. Take a look at the weather of the equator someday.
warm air=much more moisture and heavier rains. The tropics gets extreme heavy rains. A warmer earth would be a one of swamps and heavy down pours. Just picture 85-200 mya and 400-600 mya.
Wrong again boyo. The equator has a continuous low pressure gradient due to the warm air. The air rises and comes back down to Earth at around the 30 degree lattitude both north and south. Those areas are known as the Horse latitudes and the trade winds generated flow towards the equator where they die out in the doldrums. Calm light winds is the norm with lots of gentle rain showers all day long all over the place. If you're sailing through the area it sucks but if you're cruising having a good time it is simply wonderful.
That low pressure forms because of warm air converging and raising. The clouds within the tropics can be 50, 60 thousand feet and is mostly cumulonimbus clouds, which don't normal have steady rains like stratus that the pacific northwest enjoys for most of the year. These cumulonimbus clouds are convective in nature and can produce down pours...Most thunderstorms on earth occur within the tropics...Your right about the raising of the air and the sinking once you get to 25-35 north, which are where the deserts of our earth are mostly. The rain within a tropical rain forest is convective and can be very heavy indeed. I'm saying the tropics can have rains that rain inches and inches in a very short time.
