Convection is the vertical transfer of mass, heat, or other properties in a fluid or substance that undergoes fluid-like dynamics. Convection takes place in the atmosphere, in the oceans, and in Earth's molten subcrustal asthenosphere....

The process whereby material in a fluid (such as air or water) moves due to its differential density relative to other parts (generally) of the same fluid. The difference in density is caused by a difference in temperature between one part of the fluid...

Transfer of heat by the movement of molecules in a gas or liquid, with the less dense fluid rising. The majority of heat transfer in a fire is by...

Convection in the most general terms refers to the movement of currents within fluids (i.e. liquids, gases and rheids) Convection is one of the major modes of heat transfer and mass transfer. In fluids, convective heat and mass transfer take place...

The technology of toasting barrels hasn't advanced a whole lot in the past few centuries. You start a fire, plop the barrel down over the top of it, and pull the barrel off the flame when the desired tawny toast is achieved. Traditional...

ABSTRACT Convection in the world's oceans often occurs in small, semienclosed basins where bottom slopes and nearby continental shelf breaks are commonplace. The evolution of convectively generated heat anomalies in such settings is studied using quasigeostrophic finite-difference and point vortex models. The displayed...

Pollution from Asia is helping generate stronger storms over the North Pacific, according to new research. Changes in the North Pacific storm track could have an impact on weather across the Northern Hemisphere. Satellite measurements have shown an increase in tiny particles generated from coal...

The famous farm near the alfalfa field that drew 400,000 people to Woodstock for three days of sex, drugs and rock 'n' roll is up for sale.The asking price: $8 million.Roy Howard, the current owner, is packing it in after years of tangling with local...
