Convection Near Papua New Guinea - July 26th, 2011

This image shows two areas of convection near the equator, north of Papua New Guinea and West Papua, the Indonesian western half of the island of New Guinea (partially visible at the lower left). Both have a distinct, rounded shape but had not developed the wind-speed or eye structure necessary to be considered tropical depressions.

Convection is the movement for molecules within fluids (i.e. liquids, gases). It is one of the major modes of heat transfer and mass transfer. More localized phenomena than global atmospheric movement are also due to convection, including wind and some of the hydrologic cycle.
