What is the most important factor in determining the climate of a region

One thing that you have to keep in mind is the altitude. Another thing that you have to keep in mind is the proximity to the closenesss of water because they vary in the amount of condensation. Wind patterns matter because the amount of wind you have determines the temperature. If the temperature is blazing hot most likely a desert. If their is so much wind that you can harness it most likely a field where plants and animals live. Another place that hot but has alot of condensation is the jungle. Because they have lots of leaves that direct windflow through the entire place. Ocean currents matter because the waves erode the side of the land slowly destroying it. One day all land will be under the sea. Also if the water currents are nearby their is always the chance of flooding which can be good or bad. Like at cairo eqypt their nile floods once a year making rich soil to grow food and crops on. But if the floooding is to bad then the chances are the water might destroy things like my power company for instance. My power has been out for 2 days already. Using generator.
