Sentences with phrase «extratropical storm activity»

The North American east and west coastal regions are both strongly influenced by ETCs and, subsequently, land - based, coastal, and maritime economic sectors in Canada and the USA all experience strong adverse impacts from extratropical storm activity from time to time.

In this study, the potential predictability of seasonal variations in extratropical storm activity is investigated using analysis of variance to provide quantitative and geographical observational evidence indicative of whether it may be possible to predict storm activity on the seasonal timescale.

Analyses of wind and significant wave height support reanalysis - based evidence for an increase in extratropical storm activity in the Northern Hemisphere in recent decades until the late 1990s.

Not exact matches

Thus, some heat gets converted to kinetic energy, but that gets converted back to heat, either by viscosity or by thermally - indirect circulations that produce APE while pulling heat downward in the process (LHSO: Ferrel cell (driven by extratropical storm track activity), Planetary - scale overturning in the stratosphere and mesosphere (includes Brewer - Dobson circulation (I'm not sure if the whole thing is the Brewer - Dobson circulation or if only part of it is)-RRB-, some motions in the ocean; LVO: wind driven mixing of the boundary layer and of the upper ocean (though mixing itself tends to destroy the APE that the kinetic energy would create by forcing heat downward)-RRB-.

Slowing such overturning by reducing the horizontal differential heating could tend to allow heat to build up at lower levels until the lapse rate is more favorable to localized vertical overturning (LVO)(The two forms of overturning are not always completely distinct or separate; for example, the Hadley cell, Walker, and monsoon circulations, as well as extratropical storm track activity (developing from baroclinic instability (Rossby wave phenomena)-RRB- are driven and organized in part by horizontal differential heating, but in the ascending portions of these circulations, cumulus - type convection can occur).

----- 431 (57i): thermally - indirect circulations that produce APE while pulling heat downward in the process (LHSO: Ferrel cell (driven by extratropical storm track activity)...

Over 75 % of the Northeast short - term extreme precipitation is related to extratropical storms moving through or near the region, except during September, when more than 50 % of extreme precipitation is related to tropical storm activity.
