A pattern is something that repeats itself, like stripes or checkers. Sometimes the weather has a pattern as well. The job of a meteorologist, or weatherman, is to figure out what these weather patterns will do. There are two weather systems that bring changes to our weather. One of them is a “High Pressure System” while the other one is a “Low Pressure System”. Depending on how close we are to these systems can tell us what type of weather we can expect.
Low pressure systems, or cyclones, are the big weather makers. When we're underneath or close to them, our weather will be cloudy, rainy or stormy. Sometimes we may even see temperatures rise and fall rapidly. During the Winter, low pressure systems are the main cause of Winter Storms and Blizzards.
A high pressure system, or anti-cyclone, is the opposite of a low pressure. When we're underneath or close to a high pressure, our weather will be calmer and more stable. This means more sunshine, less clouds and our consistent temperatures. High pressure systems are usually responsible for heat waves during the summer season, since they can prevent the weather from changing.
