What is the relationship between air temperature and the geographical latitude of a place?

At the greatest angles, the sun’s rays fall on the Earth in the equator region and heat it more there. For this reason, the warmest regions are between the South and North tropics, the coldest regions are the Arctic and Antarctic regions. There are moderate latitudes between them, including temperature. Conclusion: the higher the latitude (both north and south), the lower the temperature. Naturally, this pattern is not mathematically rigorous. Air and ocean currents, cloud cover and other factors affect the temperature and therefore the isotherms are not located along the parallels.
