Weather is a fascinating subject. It is such an intricate and amazing process, which our mother earth goes through on a daily basis. All over the world, weather seems to be a very important aspect for our everyday lives. For instance; sunny weather can bring on a very harmonious and beautiful atmosphere, while cloudy and rainy weather can bring about tragedy. In 1998, the earth experienced an El Nino which brought on fierce weather, flooding, and hurricanes. Weather systems are very broad and detailed, so please; sit back and enjoy as I attempt to tackle the subject of weather systems. Throughout my essay, I will be using the scientific methodology in my research methods to determine what I know, what I want to know, and the many unanswered questions that exist. Before I dig any deeper into the complicated weather systems, I will first describe a very important detail to our weather drama? There is a very distinctive body of air called an air mass. This distinctive body of air is the effect of the surface on the air, which created regional, homogeneous masses of air having specific conditions of temperature, humidity, and stability. These masses of air interact to produce weather patterns.
