So I've decided to re-do my worlds winds with a more realistic approach. Honestly the entire process has overwhelmed me, so I need some help with certain things.

This is the climate map map by itself. Key:

Dark Blue = Tropical rainforests

Blue = Savannah

Red = Hot Desert

Orange = Hot Steppe

Pink = Cold Desert

Cream = Cold Steppe

Light Green = Eastern Maritime

Green = Western Maritime

Light Blue = Laurentian enter image description here

This is the pressure, wind and precipitation map for the equivalent of January on my planet. enter image description here

Yellow is seasonal high pressure, green is seasonal low pressure. Dark blue is either ITCZ or polar front, depending on latitude. Red is subtropical high zone. Blue is what I think is wet.

This is for the equivalent of July. enter image description here

You should also know that my planet orbits a star with 0.68 solar masses. Its orbit is ~178 days long, and its effective temperature is 20 degrees. Its atmospheric pressure at sea level is 1.3 atm. Its radius is 1.25 Earth radii.

Thanks for the help!

EDIT: Okay, so I’m pretty sure this means my pressure zones/winds are alright. Now I just need help filling in the last bits and pieces of the climate map. Also, does it look right?

EDIT 2: Sorry it took so long to get this done, I was caught up with life. Anyway, here is a grid to represent longitudes and latitudes. Each square up/down and left/right is 15 degrees, hopefully...

Oh and also, the Equator is 6 lines up from the bottom line.

    $\begingroup$ I have a strange feeling I am missing some important information. The first sentence seems to indicate that you have posted a question before, but I have no way of finding that question. Whenever you post, you have to remember that the vast majority of people on this site have no idea who you are. $\endgroup$ Commented Nov 27, 2020 at 17:04

    $\begingroup$ We need a better view of the topology of the mountain - height, shape, size. Methinks it woul act much like an airplane wing in terms of air pressure of the winds blowing past it. and this would determine rainfall, but this is difficult to tell. Also, the size of the island itself is important. Is it continent sized or island sized? How big are your climate zones? My back yard has 'climate zones', but not as deliniated as yours. $\endgroup$ Commented Nov 27, 2020 at 19:21

    $\begingroup$ So very conceivable that the mounain would act as an air foil, low pressure on the south side, rain on the lee side of the winds. The winds would probably not go over the mountain, but around it. There would be wind vortexes behind the mountain. Looks conceptually possible, very plausible. Good work. $\endgroup$ Commented Nov 28, 2020 at 14:49

    $\begingroup$ Depends onthe angles and the exact direction of the wind. There could possiblybe a 'atall' scenario. See mpoweruk.com/flight_theory.htm $\endgroup$ Commented Nov 30, 2020 at 3:18

    $\begingroup$ Could you show where your equatorial, tropical, and polar lattitudes are? Also what do the various lines in the oceans represent? Ocean currents? Wind directions? $\endgroup$

Well, the youtube channel Artifexian have some videos on this topic, he also deals with a more hyper realistic worldbuilding that you might be interest.
