When I learned about weather patterns, I learned about air masses, weather and more. I learned that air masses are groups of air with similiar temperature, pressure and humidity. I learned that when different air masses meet, that can cause storms, fronts and wind. I learned that air and ocean currents can affect global weather by having the wind move the ocean currents and the ocean currents may bring along different temperatures which then can change the weather. I also learned that weather maps are maps that show what weather is like in an area.
