a) The horizontal map corresponds to an uneven spatial distribution on Earth’s sphere. b) The geopotential height is closely related to the latitude. c) The mean wind speed and temperature are closely related to the height (formulated as pressure levels). Sub-figures b) and c) were plotted using statistics on the ERA5 data.
