Atmospheric convection. Atmospheric convection is the result of a parcel-environment instability, or temperature difference, layer in the atmosphere. Different lapse rates within dry and moist air lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threa

Redistribution of Heat Key idea: Planets are not evenly heated by the Sun. The uneven heat is redistributed my moving air masses, water vapor and ocean currents (on Earth anyway). The non-uniform heating and the redistribution of heat produce global circulation of the atmosphere, global climate and local weather patterns.

Also, shine a flashlight on a large ball or globe and observe where the intensity is largest and smallest. Rotate the ball as the Earth spins on its axis and observe that the highest intensity is always in the vicinity of the equator. The uneven heat energy from the Sun is redistributed by moving air masses, water vapor and ocean currents.

Mantle convection is the slow creeping motion of Earth's rocky mantle caused by convection currents carrying heat from the interior of the earth to the surface. It is one of 3 driving forces that causes tectonic plates to move around the Earth's surface.

Heat transfer by natural convection plays a role in the structure of Earth's atmosphere, its oceans, and its mantle. Discrete convective cells in the atmosphere can be seen as clouds, with stronger convection resulting in thunderstorms. Natural convection also plays a role in stellar physics.

While less dynamically important than in the atmosphere, such oceanic convection is responsible for the worldwide existence of cold water in the lowest layers of the ocean. Initiation A thermal column (or thermal) is a vertical section of rising air in the lower altitudes of the Earth's atmosphere. Thermals are created by the uneven heating of the Earth's surface from solar radiation. The Sun warms the ground, which in turn warms the air directly above it. The warmer air expands, becoming less dense than the surrounding air mass, and creating a thermal low.

The uneven Solar heating and the redistribution of heat energy leads to global circulation of the atmosphere, global climate and local weather patterns. The weather therefore results from the response of a planet and its atmosphere to uneven heating from the Sun and the attempt to move that heat from hotter areas to cooler areas!!!

Convection is the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock (rheid). Convection takes place through advection, diffusion or both. Convection cannot take place in most solids because neither bulk current flows nor significant diffusion of matter can take place.
