Sentences with phrase «into updraft»

The authors explain how adults» subliminal perceptions of students based on characteristics such as race, class, gender, and demeanor can result in the sorting of students into updraft and downdraft tracks.
For convection, we could separate the amount of energy transfered vertically into updrafts and downdrafts.

Not exact matches

Fire whirls arise when superheated air above a wildfire drives strong updrafts and downdrafts that get sheared by the wind, causing them to twist into a vortex that funnels flames upward.
11 Roll clouds form when updrafts and downdrafts churn clouds into a long, spinning cylinder.
The intensity of the downdrafts and updrafts is vital, because in the end there needs to be a lot of stretching, which is when you take that existing rotation and turn it into something really violent like a tornado.
But for a tornado to form, you still need to tilt the rotation into the vertical, and this requires a nearby updraft.
The sudden increase in lightning is one sign a normal storm is rapidly evolving into a supercell, with a large rotating updraft — or mesocyclone — at its heart.
Supercell thunderstorms occur when the warm updraft punches through an overlying, stable layer and continues upward into a zone of cool, dry air.
As the updraft moves, it rotates; if the rotation grows sufficiently intense, the storm can evolve into a tornado or funnel cloud (a tornado whose bottom does not touch the ground).
The storms» violent updrafts sucked in air that shot up 40,000 - 50,000 feet or more into the atmosphere.
Turbine exhaust steam condensing (to renew the Rankine cycle) conventionally involves wet cooling, where cooling water from the shell - and - tube steam condensers is sprayed into cooling towers, and an updraft carries vapor from evaporative cooling into the atmosphere.
These coupled with the increased intrusion of the tropopause into the stratosphere appears to cause a change in the saturated adiabatic proccess and allows a greater updraft resulting in an increase in the fall distance of the condensensing water vapor resulting in high average winds and lower eye pressures.
Anderson and his colleagues start with a new and unexpected observation, based on high - altitude flights and satellite measurements: powerful updrafts from powerful summer thunderstorms can send moisture much higher into the stratosphere than anyone had thought.
Every now and then, however, the shear is low and a cluster of thunderstorms joins up and creates a persistent updraft as warm wet air is pulled into the low pressure underneath, is lifted up (cooling), and falls back as much cooler rain.
