Since the center of the Earth gets more sunlight, it is consistently hotter than other parts of the Earth. When air is hot, it rises. It creates low-pressure areas that draw air from other areas in, creating wind. This heating and cooling of the air on Earth causes all the climate and weather patterns we know. The reason we have global wind patterns is ultimately due to a differentially heated, rotating Earth. The differential heating of Earth continually causes an imbalance in air pressure and temperature around the world, which in turn causes a continuous general circulation of winds that attempt to restore balance. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in an upward current of air and can cause thunderstorms and other natural calamities or change in weather.
