Exercise #3 Lower layer has ____/8ths coverage. Prevailing visibility is statute miles. Middle layer has ____/8ths coverage. Sector visibility and direction (if any). Upper layer has ____/8ths coverage. Total sky coverage is ____/8ths. Given: Altimeter: 29.839 inches Sea-level pressure: 994.5 hPa Wind indicator has direction of 140°, speed is 12 knots. Dry bulb temperature is 86.7°F; wet bulb temperature is 80.2°F Computed dew point is °F. No thunder has been heard, however, lightning is observed striking the ground approximately 6 miles North of the station at a rate of 1 to 6 flashes per-minute. A light rain shower is falling at the station. Cumulonimbus clouds are observed overhead in the layer at 8,000 feet and are moving east. The last element was observed at 1254 UTC. 9-3
Exercise #4 Lower layer has ____/8ths coverage. Prevailing visibility is statute miles. Upper layer has ____/8ths coverage. Sector visibility and direction is (if any). Total sky coverage is ____/8ths. Given: Altimeter: 29.871 inches Sea-level pressure: 995.8 hPa Wind indicator has direction of 170°, speed is 6 knots. Dry bulb temperature is 92.2°F; wet bulb temperature is 78.7°F Computed dew point is °F. The last element was observed at 1351 UTC. 9-4
