Answer:
Although many factors combine to influence weather, the four main ones are solar radiation, the amount of which changes with Earth's tilt, orbital distance from the sun and latitude, temperature, air pressure and the abundance of water.
Solar Distance : Earth's distance from the sun changes throughout its orbit, resulting in up to a 4 degree Fahrenheit difference between the closest and furthest points. The oscillating tilt of the planet creates much larger weather effects, because the tilt toward or away from the sun over the course of the year determines the amount of heat that part of the planet will receive. When a hemisphere is tilted toward the sun, that part of the planet experiences summer, whereas when it is tilted away, winter.
Latitudinal Location : Where on Earth you are also affects the weather. At the equator, for instance, weather does not change much, because that latitude always receives roughly the same amount of sunlight: around 12 hours a day. As you move away from the equator, however, you receive more or less sunlight, depending on the season. Polar regions experience extremely long days in summer and extremely long nights in winter. Both summer and winter temperatures also cool gradually as you move north or south of the equator.
Air Pressure : Solar radiation heats the planet, but it does not do so evenly. Air pressure is influenced by the differences between hotter and cooler pockets of air, or fronts. When the pockets are very different in temperature, they try to mix together, creating movement and pressure. When they aren’t very different, the atmosphere moves around less -- resulting in, usually, fewer weather effects. As air attempts to equalize by moving from high pressure areas to low pressure areas, this causes wind. Additionally, when pressure is low, air is rising, which often means moisture accumulation in the atmosphere. Moisture accumulation forms clouds, which then produce rain or snow -- depending on air temperature -- once they get to their saturation point. When atmospheric pressure is low, air is pushed down toward the surface, meaning rain and moisture don't accumulate. This often also leads to high humidity near the surface of the Earth, where people experience weather.
Water Presence : The presence of water has a significant impact on weather. Nearby bodies of water add moisture to the atmosphere in the form of evaporation, which is why places near oceans or lakes, for instance, are usually wetter than the desert. Additionally, large bodies of water create winds as temperature differentials between land and water send breezes inland during the day and out to sea or onto lakes at night. Evaporating water forms different types of clouds: cirrus, which are high in the atmosphere and made of ice, stratus, which form lower down and consist of a thick, white blanket of rain drops, and cumulonimbus, which pile high and signal harsh weather, such as thunder, lightning, hail and tornadoes.
