After a snow shower, the small amount of dry snow on the ground is being lifted by rather strong winds. The snowrestricts horizontal visibility to 2000 m between the ground and a height of about 50ft. In a METAR, this should bereported as...
A high pressure that is weakening with altitude and turns into a low is called a:
Which FL corresponds with the 500 hPa pressure level?
The sinking of air is favoured...
In a large area covered by an air mass of uniform density and situated in the northern hemisphere, isobars on the weather map are equidistant. In this case, geostrophic wind speed..
By volume, what percentage of the air in the lower troposphere consists of water vapour?
Visibility is reduced by water droplets to 1 200 m. What is this classified as?
According to ISA the temperature in the lower part of the stratosphere..
You must make an emergency landing at sea. The QNH of a field on a nearby island with an elevation of 4 000 ft is 1025 hPa and the temperature is -20°C. What is your pressure altimeter reading when landing if 1025 hPa is set in the subscale? (Barometric lapse rate: 27 ft/hPa)
The vertical extent of the friction layer depends primarily on..
