[5][2] Thermal radiation reflects the conversion of thermal energy into electromagnetic energy. Thermal energy is the kinetic energy of random movements of atoms and molecules in matter.
e. A weather front is a boundary separating air masses for which several characteristics differ, such as air density, wind, temperature, and humidity. Disturbed and unstable weather due to these differences often arises along the boundary. For instance, cold fronts can bring bands of thunderstorms and cumulonimbus precipitation or be preceded ...
Sea breeze. Schematic cross section through a sea-breeze front. If the air inland is moist, cumulus often marks the front. A sea-breeze front is a weather front created by a sea breeze, also known as a convergence zone.
