Hydrologic Cycle Relative Humidity The ratio between the actual amount of water vapor held in the atmosphere compared to the amount required as long as saturation. It is influenced by temperature.

Humidity Humidity: water vapor content of air Capacity primarily a function of temperature Relative humidity (RH) (actual water vapor content) (max. water vapor capacity of the air) RH affected by evaporation/condensation temperature x 100 Saturation vs Air Temperature The actual amount of Water air can hold changes With air temperature Air at 104 F can hold 3 times As much water as 68 F air ! (47 grams vs only 15 grams) Air at 68 F can hold 4 times As much water as air at 0 F (15 grams vs only 4 grams) 32 F 68 F 104 F 4 grams 15 grams 47 grams Relative Humidity Examples Examples At 22 ºC (72 ºF), one kg of air can hold 50 grams of water vapor. RH if holding 25 grams 50 grams 60 grams What happens if water is added Removed What happens to RH if temp. drops Increases

Saturation in addition to Dew Point Saturated v. unsaturated air Dew-point temperature temperature to which air must be cooled to reach saturation (100% RH) water on outside of glass ice on your car window Adiabatic Cooling: Clouds in addition to Condensation Cloud base = dew point altitude Relative Humidity in addition to Temp. RH fluctuates over a day or season.

Measuring Relative Humidity Sling psychrometer Hair hygrometer After Saturation Occurs the Air Must Release Extra Water as Fluid Water as long as ms on the outside of a cold glass as the cold Air surrounding the glass chills the air to the Dew Point Temperature The resulting water is not from the glass, the water is from condensation of moisture in the air around the glass In Nature Extra Moisture is Trans as long as med to Water Droplets Cold air next to the rain-soaked cliff is chilled To The Dew Point Temperature & creates a Misty Cloud along a Rocky Mountain slope Air near the Slope is 100% Saturated

Fog: A Cloud on the Ground Fog by San Francisco Bay This Advectional fog as long as ming in San Francisco is due to Moist Ocean air being moved horizontally over cooler l in addition to surfaces This fog is a common Summer condition Along the Cali as long as nia coast As high temperatures Farther inl in addition to draw moist ocean Air over coastal areas Yakima River, Washington

Valley Fog in the Valleys of the Appalachian Mountains Valley Fog: Distributed by Topography An often Very dense Type of Valley Fog Called Tule Fog in the Central Valley of Cali as long as nia Pacific Ocean Temperature Inversions When warmer air overlies cooler air, pollutants in addition to fog are trapped beneath the inversion. Common Winter Radiation Inversion in Valleys

Temperature Inversions Common Summer Inversion in Los Angeles Types of Lifting of Air Air Lifting processes create clouds & clouds Are the only means of precipitation on Earth Four types of lifting are recognized: Convergent Lifting Convectional Lifting Orographic Lifting Frontal Lifting Convergent Lifting of Air Convergent Lifting occurs When Air masses meet & are as long as ced To rise vertically This process is best seen at The Equator where the Trades Winds Meet & rise to as long as m towering Clouds & heavy Precipitation

Convergent Lifting & Global Precipitation Patterns Convergent Lifting provides the greatest amount of Precipitation On Earth Near the Equator Shown In dark Green on This map Local Convectional Lifting Anywhere the L in addition to is warmer Air will rise In this example A plowed field Creates warmer Air temperatures Than nearby Green cropl in addition to & Local air rises Convectional Lifting Over Florida Warmer temperatures over the peninsula of Florida, which is l in addition to , cause air to rise compared to the cooler oceans nearby Rising air in this Shuttle Picture is Shown by a Cloud pattern which generally follows the shape of the southern Florida peninsula

Orographic Lifting of Air When air moving Horizontally Encounters a Mountain it must Rise over the crest As it rises, it cools To create clouds, And most often precipitation Moist Air Moisture Lost Dry Air Run off NO Run off The Orographic Effect Wet (Windward) Side Dry (Leeward) Side Along the west coast of United States air moving eastward From the ocean contains moisture – as this air moves over The coastal mountains, clouds & precipitation occur Leaving Only dry air on the inl in addition to side of the mountains Frontal Lifting of Air Although not a mountain range, masses of moving air Create the same effect – Unlike mountains air masses Can provide lifting in many different locations Fronts can lift air Which is stable, Creating clouds & large amounts Of precipitation As rain, snow, Sleet or hail

Seasonal in addition to Global Variation in Lifting Mechanisms in addition to Precipitation Convective – increases when insolation is most intense in addition to when marine air moves over l in addition to masses Orographic – requires elevation change Frontal – midlatitudes only Convergent – near ITCZ only Summary Humidity Relative Humidity Relationship to Temperature Dew Point LCL Precipitation (Rain, Snow, Sleet, Hail) Ice Crystal Process, Collision-Coalescence Lifting Mechanisms Convective, Orographic, Frontal, Convergence Atmospheric Stability
