What is the role of latitude in climate variation?

Latitude plays a crucial role in climate variation by influencing the intensity and angle of sunlight received at different locations on Earth. Areas near the equator experience direct sunlight, resulting in warmer temperatures year-round, while regions at higher latitudes receive sunlight at more oblique angles, leading to cooler climates and distinct climatic zones: tropical, temperate, and polar^[1][3][4].

The Earth's axial tilt also impacts the distribution of solar energy, which affects atmospheric circulation and seasonal changes. As latitude increases, average temperatures decrease, with polar regions experiencing the coldest conditions due to minimal direct sunlight and longer winter nights^[2][3][4].
