A dry line (also called a dew point line, or Marfa front, after Marfa, Texas) [1] is a line across a continent that separates moist air and dry air. One of the most prominent examples of such a separation occurs in central North America , especially Texas, Oklahoma, and Kansas, where the moist air from the Gulf of Mexico meets dry air from the ...
The dry line normally moves eastward during the day and westward at night. A dry line is depicted on National Weather Service (NWS) surface analyses as an orange line with scallops facing into the moist sector. Dry lines are one of the few surface fronts where the pips indicated do not necessarily reflect the direction of motion. [18]
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
Outflow boundary on radar with radial velocity and frontal boundary drawn in.. An outflow boundary, also known as a gust front, is a storm-scale or mesoscale boundary separating thunderstorm-cooled air from the surrounding air; similar in effect to a cold front, with passage marked by a wind shift and usually a drop in temperature and a related pressure jump.
A virga, also called a dry storm, is an observable streak or shaft of precipitation that evaporates or sublimates before reaching the ground. [1] A shaft of precipitation that does not evaporate before reaching the ground is known in meteorology as a precipitation shaft .
There's the science of Santa Ana winds and then the mythology as these winds weave in and out of Southern California memory. "There was a desert wind blowing that night.
The dry line is the boundary between dry and moist air masses east of mountain ranges with similar orientation to the Rockies, depicted at the leading edge of the dew point, or moisture, gradient. Near the surface, warm moist air that is denser than warmer, dryer air wedges under the drier air in a manner similar to that of a cold front wedging ...
Termination Shock is a science fiction novel by American writer Neal Stephenson, published in 2021.The book is set in a near-future when climate change has significantly altered human society and follows the attempts of a solar geoengineering scheme.
