Trade winds blow from the Subtropical High-Pressure belts (around 30° N and S) toward the Equatorial Low-Pressure belt (the ITCZ). These winds are constant and reliable, blowing from the northeast in the Northern Hemisphere and the southeast in the Southern ...
The Wet Adiabatic Lapse Rate occurs when rising air becomes saturated and water vapor begins to condense into liquid droplets. This condensation releases “latent heat,” which warms the surrounding air. Consequently, saturated air cools more slowly (about 5°C per km) ...
The ozone layer specifically excels at absorbing UV-B radiation (280–315 nm). While it absorbs all UV-C radiation (the most dangerous), UV-B is the wavelength that partially reaches the surface and causes sunburn, skin cancer and cataracts. By absorbing most of ...
The twinkling of stars, known as stellar scintillation, is caused by atmospheric refraction. As starlight passes through different layers of the atmosphere with varying densities and temperatures, the light is bent multiple times. Since the atmosphere is constantly moving due ...
