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.
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.
In many real-life applications (e.g. heat losses at solar central receivers or cooling of photovoltaic panels), natural and forced convection occur at the same time (mixed convection). [4] Internal and external flow can also classify convection. Internal flow occurs when a fluid is enclosed by a solid boundary such as when flowing through a pipe.
When the convection is strong linear or curved, the MCS is called a squall line, with the feature placed at the leading edge of the significant wind shift and pressure rise. [2] This feature is commonly depicted in the warm season across the United States on surface analyses, as they lie within sharp surface troughs.

The museum had exhibits on Texas history, anthropology, geography, and ethnography, but these were relocated to other museums (including the Bullock Texas State History Museum) in 2001. In October 2013, Linda Hicke, the dean of Austin's College of Natural Sciences , cut the museum's funding by $400,000.
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.
In meteorology, a heat burst is a rare atmospheric phenomenon characterized by a sudden, localized increase in air temperature near the Earth's surface. Heat bursts typically occur during night-time and are associated with decaying thunderstorms. [1]
