Atmospheric convection is the vertical transport of heat and moisture in the atmosphere.It occurs when warmer, less dense air rises, while cooler, denser air sinks. This process is driven by parcel-environment instability, meaning that a "parcel" of air is warmer and less dense than the surrounding environment at the same altitude.
The center of the storm continued to drift to the east-southeast into the early hours of August 29, but never strayed more than 70 mi (110 km) away from the Texan coast. Convection blossomed again later that day, with the center jumping northwards into the convection as Harvey began moving to the northeast.
1997 – The Pacific Decadal Oscillation was discovered by a team studying salmon production patterns at the University of Washington. [ 78 ] [ 79 ] 1998 – Improving technology and software finally allows for the digital underlying of satellite imagery, radar imagery, model data, and surface observations improving the quality of United States ...

Convection is often categorised or described by the main effect causing the convective flow; for example, thermal convection. Convection cannot take place in most solids because neither bulk current flows nor significant diffusion of matter can take place. Granular convection is a similar phenomenon in granular material instead of fluids.
Southeast Texas has been hit with heavy rains and rising rivers, leading to school closings, high-water rescues and mandatory evacuation orders in some areas. Here's a look at the situation ...
On August 12, 1990, Susan Hendrickson -- a fossil hunter -- discovered three huge bones protruding out of a cliff near Faith, South Dakota. Those burned turned out to be part of the largest ever T ...
A warmer air mass moving over a cooler one can "shut off" any convection which may be present in the cooler air mass: this is known as a capping inversion. However, if this cap is broken, either by extreme convection overcoming the cap or by the lifting effect of a front or a mountain range, the sudden release of bottled-up convective energy ...
