But there is increasingly frequent respite in the form of warm "foehn wind
In Wales, the temperature in Llanfairfechan soared to 220C by yesterday afternoon, with a Foehn wind
blowing down the mountains to make it warm.
A similar temperature was recorded at Llanfairfechan with a warm Foehn wind
blowing down the mountains.
Depending on the temperature of the air mass, the Santa Ana wind emerges to the lee of the mountains as either a cold foehn wind
or a warm chinook wind.
"Chinook" is derived from an Oregon Native American word meaning "snow eater." The chinook is a foehn wind
occurring in the Rocky Mountains.
Temperatures in Hualien and Taitung in eastern Taiwan could top 38 degrees on Saturday due to possible foehn winds
- warm and dry gusts that flow down the sheltered side of mountains into valleys - the bureau said.
affect local weather and climate and impact agriculture (growing conditions due to temperature and humidity changes; top soil erosion), tourism (reliable spots for wind and kite surfing), artificial snow making (change of wet-bulb temperatures), air pollution (trapping pollutants in cold pools underneath the foehn layer, or sweeping them away in case of breakthrough), human health (reduction of air pollution), forest fires (intensifying them to uncontrollable extents), ground traffic (toppling trucks; snow or sand drifts; blasting of vehicles with sand and small rocks), and air traffic (closure of runways when crosswinds are too high).
The appearance of this hot, dry air was accompanied by strong western foehn winds
blowing along the lee side of the Judean Mts.
These are known as Foehn winds
, and their warming and drying effect - the Foehn effect - can be striking and farreaching."
The foehn winds
coming from the Western Carpathians and reaching the large valleys found in the Tarnave region also have a significant contribution in terms of temperature.
Today a latent poetry echoes in the names we use to distinguish foehn winds
from gravity airflows and Katabatic winds from the Khamsin.
