Exercise #9 Lower layer has ____/8ths coverage. Prevailing visibility is statute miles. Middle layer has ____/8ths coverage. Sector visibility and direction is (if any). Upper layer has ____/8ths coverage. Total sky coverage is ____/8ths. Given: Altimeter: 29.782 inches Wind indicator has direction of 190°, varying from 160° to 220°, speed has suddenly increased from 10 to 28 knots gusting to 40 knots. Dry bulb temperature is 88.5°F; wet bulb temperature is 83.1°F Computed dew point is °F. Rain is moderate and thunder was first heard at 1835 UTC. Cumulonimbus clouds are observed in the vicinity to the southwest at 5,000 feet and towering cumulus are overhead in the layer at 1,800 feet. All clouds are moving northeast. The time of the observation is 1835 UTC. 9-9
Exercise #10 Total sky coverage is ____/8ths. Prevailing visibility is 3/8 statute miles. Given: Altimeter: 29.837 Sea-level pressure: 995.4 Wind indicator has direction of 70°, speed is 5 knots. Dry bulb temperature is 30.9°F; wet bulb temperature is 29.7°F Computed dew point is °F. Visibility is varying between 1/4 and 1 mile in moderate freezing rain. The last element was observed at 1856 UTC. 9-10
