Here are the steps to convert the barometric pressure code to millibars:1. If the first digit is 5 or greater, add 1000.2. Place a decimal point before the last two digits. So for 887:1. The first digit (8) is not 5 or greater, so do not add 1000.2. Place a decimal point before the last two digits.887 = 988.7 millibars

97. The Formation of Clouds A. Define cloud:large group of H2O droplets suspended in air B. Steps involved in cloud formation: warm moist air rises expands cools condenses
98. 1. Describe the mass of air that would lead to cloud formation in terms of temperature, humidity, density Warm Moist Low density
99. 2. The air will risebecause of low density 3. Describe what the air does as it rises: expands cools condenses
100. 4. Clouds will form if this rising moist air a. cools to the dew point temp. b. has condensation nuclei available. (dust, pollutants etc..)
101. C. Basic Cloud Types: 1. Cirrus: high and feathery (fair weather) 2. Cumulus: white and puffy (fair weather) 3. Stratus: covers the sky like a blanket (precipitation probable)
106. D. Effects of aMountain Range: OrographicEffect (adiabatic cooling)
107. Condenses Dry air cools Sinks expands Wind compresses warms Moist air rises mountain
108. 1. The side of the mountain with the moist prevailing winds is called the _____________ Summary: Windward side moist air rises expands cools condenses Wind
109. 2. The air descends to the otherside of the mountain which is called the ______________________ Summary: Leeward side dry air sinks compresses warms Wind
110. D. Precipitation A. Describe what causes precipitation: Precipitation forms around Dust particles (pollutants) droplets combine (coalesce)become heavy and fall
111. B. Explain why precipitation cleans the atmosphere: as precipitation forms around dust/pollutants…they are removed from theatmosphere as precipitation falls
112. When the dew point temperature and air temperature approach each other what happens to the chance of precipitation and why? The chance of precipitation increases because the air is more saturated
113. E. Complete the chart below: Warm moist Rise Expand Decrease Decrease Cool Sink Compress Increase Increase
115. Dew Point Temperature The temperature at which the air is holding the ____________ amount of water. The air is _____________ Maximum saturated
116. Relative Humidity: The ratio of the amount of water vapor in the air, to the maximum amount it can hold. It is usually expressed as a __________. As the temperature increases, the maximum absolute humidity _____________ but the relative humidity will decrease percentage Stay the same,
117. The dew point and relative humidity are determined by using an instrument called a _______________________ sling psychrometer
118. The psychrometer has two thermometers, a dry bulb and a wet bulb. The psychrometer is whirled in the air so that evaporation will occur.
119. The lower the moisture content of the air, the ________ evaporation will occur from the wet bulb and the wet bulb temperature will be _________ more lowered
