I have a metereology question?
Undergraduate meteorology majors earn a Bachelors of Science (BS) degree which requires math courses through Calc 3 and ordinary differential equations along with calculus-based Physics I and II. If you can't pass the rigorous math courses then you can't earn a BS and you can't work as a degreed meteorologist unless maybe in a watered-down ... less math intense program ... such as a Bachelors of Arts ... and work as a broadcast meteorologist or climatologist.
FWIW (not much), I never took calculus at all. My degrees are not in meteorology but I breezed through the USCGAux weather qualification. Nowadays, everything is computerized, so you just need to be able to understand the programs. Yes, I realize that I am not a professional meteorologist but you do have to understand climatology in my field of work.
Yes, these days you probably CAN become meteorologist or a scientist even if you struggle with math. I always have struggled with math because of math testing anxiety. It took me a long time to realize and understand that I am NOT stupid or dumb in math. I am slow because I am translating a symbolic language into terms I understand. It took me time to understand HOW the math applies to REAL problems. Sometimes there is NOT a solution. These days computers usually do the math for you. It helps if you understand HOW computers work. Some things are NOT quantifiable. Beware of GIGO, garbage in, garbage out in computer models. You have the equivalent of a work station 25 years ago in your pocket.
If you can do calculus you can be a meteorologist, I don't think you have to go any higher than that. I imagine if you were just ok in calc, you could still make it as a meteorologist ... If you couldn't do calc then you might have difficulties being a meteorologist. Hope this makes sense.
