afterwinds การใช้

• This causes turbulence and a vortex that sucks more air into its center, creating external afterwinds and cooling itself.
• When the detonation altitude is low enough, these afterwinds will draw in dirt and debris from the ground below to form the stem of the mushroom cloud.
• The particle sizes range from submicrometer-and micrometer-sized ( created by condensation of plasma in the fireball ), through 10 500 micrometers ( surface material agitated by the blast wave and raised by the afterwinds ), to millimeter and above ( crater ejecta ).
• As it rises, a Rayleigh Taylor instability is formed, and air is drawn upwards and into the cloud ( similar to the updraft of a chimney ), producing strong air currents known as " afterwinds ", while, inside the head of the cloud, the hot gases rotate in a toroidal shape.
