The Walker Circulation (tropical near-surface winds blowing from east to west, and upper-level winds
blowing from west to east) is substantially weakened, as we expect during a strong El Nino.
El Nino is a warming of the water in the Pacific Ocean that causes strong westerly upper-level winds
in the tropical Atlantic.
that have been sending smoke to the south were forecast to switch overnight and bring the haze north over Lane County and beyond today through the end of the week.
Until a few days ago, we've been in a pattern unfavorable for tornadoes, in general because the upper-level winds
over the central part of the U.
3] ANVIL: Upper-level winds
blow the top of the cloud away from the thunderstorm.
The upper-level winds
caused the storm system to rotate, meteorologist Jeff Masters, director of the website Weather Underground, told National Geographic's website.
Coastal Carolina researchers, working closely with counterparts at North Carolina State University, will evaluate the buoy data to help pinpoint the best location for the platform, which will measure upper-level winds
more similar to those a wind turbine would encounter.
The Flex Tracks programme is particularly significant for ultra long-haul flights where weather reports of upper-level winds
are regularly updated in-flight, allowing significant fuel burn and time savings to take place.
On top of that, we blew off (no pun intended) upper-level winds
, a 200-pound-fuel miscalculation.
The mid- and upper-level winds
steering the thunderstorms were weak, allowing the storms to linger in one spot and drop heavy rain, forecasters said.
The lofty vantage point will enable scientists to survey the tops of hurricanes, where upper-level winds
help steer storms.
Vallee also said upper-level winds
have continued to blow from the west, and they have torn apart fledgling storms moving east in the Atlantic Ocean.
