If you start looking at questions like, "What is the weather going to be like tomorrow?", then you are starting to ask a weather question. Weather is classified as the outdoor atmospheric activity occurring because of different temperature and moisture levels in different areas, which meet and cause weather changes. Weather focuses on atmospheric activity in one specific period in time. Climate and weather are directly connected because the weather patterns create the climate classification of the area.
The weather can be altered be different atmospheric pressures colliding. Also, the earth’s temperature affects the atmospheric pressure in different areas, too. Take a mountain as an example. When you are at the bottom, you are in normal pressure and the temperature is warmer. As you go up the mountain, the temperature decreases and so does the air pressure. The earth you stand is cooler and the air is thinner, making it prime for a snowy climate, even if down below, there is a warm, tropical rainfall climate.
Weather conditions are usually classified by the current activity in the area; for example, some classifications are wind, cloud, rain, snow, fog, and storms. Other occurrences such as tornadoes, hurricanes, monsoons, and ice storms are also included in the weather classification.
