You have an advantage in changing your major to meteorology. This major requires candidates to have a good foundation in mathematics, physics and chemistry. I wonder how old you are now. I suggest you start to study the core courses of atmospheric science, the main subjects: atmospheric science and environmental science. Main courses: introduction to atmospheric science, introduction to earth science, atmospheric physics, atmospheric exploration, meteorology, atmospheric dynamics, modern climatology, etc.
