1 Sec A Atmospheric Moisture I. Measuring Relative Humidity A. A Psychrometer is an instrument for measuring relative humidity B. A common psychrometer uses two thermometers with a wet gauze wrapped over the bulb of one. Air is blown over both thermometers and the difference in temperature between the two thermometers can be used to calculate the Relative Humidity. C. For Example the dry-bulb thermometer reads 25 degrees C and the wet-bulb reads 20 degrees C, the relative humidity is 63%. This is commonly found in a table that comes with the psychrometer. 1 II. A. Clouds form when the air is as cold as the dew point and the water vapor in the air condenses onto microscopic dust particles. Need 1. water vapor, 2. condensation surface, and 3. cooling. B. Clouds are classified by their shape and altitude. C. There are three main types of clouds: cumulus, stratus, and cirrus 1. Cumulus Clouds (SC,AC,CC,CU,CB) a. Look like piles of white cotton balls. b. Usually have flat bottoms c. Form at 2.4 to 13.5 kilometers. c. Cumulonimbus clouds are large cumulus clouds that are grey and usually bring rain d. The suffix...nimbus means rain. 2 Sec A 2. Stratus clouds (STratus, AS:AltoStratus, CS:CirroStratus) a. Large flat clouds often covering whole sky b. Form at about 2.5 kilometers c. Can bring light rain or drizzle d. Nimbostratus are stratus clouds that are raining e. Stratus clouds close to the ground are called fog. f. Our fog in SJ and Santa Cruz is called Pacific Stratus g. Ground fog forms when the ground cools quickly at night causing the temperature of the air in contact with ground to go below the dew point. Fog is usually as stratus cloud. Cirrus Clouds (CI, CS, CC) a. light feathery clouds that form at very high altitudes between 6 and 12 Km. b. made of ice crystals c. usually indicate rain or snow is coming 4. Naming of clouds a. The three types cumulus, stratus, and cirrus b. add nimbus after the word or put nimbo before the cloud type to indicate it is raining or threatening rain. c. add alto before the word to indicate high d. add cirro before the cloud type for very high 3 4 1

5 The Bottom of clouds are called their bases The Base of Cumulus Clouds( CU) can be approximated by: H ~= 1000ft x (T Tdp)/4.5 o F Fahrenheit Degs Where H is the height in feet of the Base of the CU above the surface. So Altitude of base of CU is: Alt ~= Field Elevation ft x (T Tdp)/4.5 o F Or Alt ~= Field Elevation ft x (T Tdp)/2.5 o C Celsius Degrees T is the OAT(Outside Air Temperature ) at the field Tdp is the dew point temperature at the air field See: Atmospheric Moisture:Visibility Tower Visibility: Horizontal Visibility from the tower. Prevailing Visibility: Greatest horizontal visibility which bright lights or large objects can be seen. Statute Miles Runway Visibility: Horizontal Visibility of a bright objects down a given runway. Given in Hundreds of feet. Ceiling: the height above the Earth s surface of the lowest cloud layer that has 5/8 or greater sky coverage. Vertical Visibility: The vertical distance you can see into a ground based obsuration: fog, smoke, ash, or haze. Reported in Hundreds of feet eg. VV Flight Rules VFR: Visual Flight Rules Ceiling > 3000 feet AGL Visibility > 5 Statute Miles MVFR: Marginal Visual Flight Rules Ceiling 1000 to 3000 feet AGL Visibility 3 to 5 SM IFR: Instrument Flight Rules Ceiling: 500 to 1000 Feet AGL Visibility: 1 to 3 SM LIFR: Low Instrument Flight Rules Ceiling < 500 Feet AGL and/or Visibility < 1 SM 19 Atmospheric Moisture:Precipitation Precipitation A. Water vapor that has condensed and fallen to Earth as rain, sleet, snow or hail. B. Start as very small droplets and then hit and combine with other droplets to become larger. C. A rain drop contains about 1 million times the water as a droplet in a cloud D. Frozen rain is called sleet E. Snow is a six pointed crystal F. Snow forms when water vapor changes directly to a crystal. G. Hail is like large sleet ranging in size from.5 to 7.5 cm. 1. Hail is like an onion: it has several layers from raindrops hitting it and freezing on it. 2. Can be up to 3 inches in size. 20 5
