Question 182-23 : A cold air pool can be best identified by means of ?

The isohypses on an upper air chart.

Isohypses contour lines are drawn on a constant pressure chart therefore they indicate the true altitude of a pressure level on an upper air chart as it includes temperature and wind indications you can easily identify a cold air pool you will have an area with light or no wind low temperature

South.

We know that the wind blows parallel to the isobars we can see a warm front c a cold front a a warm sector b and a cold occlusion d note it's a cold occlusion since the line of the occlusion is approximately along the same line as the cold frontwith the cold occlusion and the warm sector it's a depression located in the northern hemisphere over the sea angle between wind direction and isobars changes by 10° value to be used in examinations we can assume that the wind direction at point 'f' is south

Question 182-36 : For the planning of a flight with an estimated time of departure 0930 local time from an european airport a satellite picture is used to locate areas of fogwhat type of satellite imagery available with observation time close to etd does provide most likely the best information to locate these areas ?

Visual vis and infrared ir polar orbiting system.

Polar orbiting satellites orbit the earth at an altitude of approximately 850 km since they complete one orbit every 105 minutes the satellites circle the earth 14 times a day because of the orbital shift resulting from the planet's rotation they move west by approximately 2 time zones per orbitvisual this is basically a photo of the clouds and is only available during daylight hoursinfra red measures the heat thermal footprint of areas of cloud or the earth's surface if clouds are thin or absent and can be used both day and nightgeostationary satellites orbit the earth at about 36000 km of altitudeover the equator they are called geostationary because their position does not change with respect to a point on the surface of the earthpolar orbiting satellites are close to the surface they provide the best information to locate a small area of fog
