Warm-Up Activity
3
Aerosol-Cloud-Climate Interactions
4
Aerosol 1 : a suspension of fine solid or liquid particles in gas
5
Cloud 1 : a visible mass of particles of condensed vapor (as water or ice) suspended in the atmosphere of a planet (as the earth) or moon
6
Climate 2 a : the average course or condition of the weather at a place usually over a period of years as exhibited by temperature, wind velocity, and precipitation
7
Aerosol-Cloud-Climate Interactions AerosolCloud Climate Direct Effect Indirect Effect
8
The sun emits short- wave radiation towards to earth The Earth re-emits long-wave radiation back towards space Fun Fact Without Earth's atmosphere, temperatures would climb to over 2000°F (93°C) during the day and fall to 280°F (138°C) below zero at night.
9
Direct Effect Aerosol Climate Aerosols scatter solar radiation
10
Direct Effect Aerosol Climate Aerosols absorb terrestrial radiation
11
Light Scattering Demonstration
12
Clouds-Climate Cloud Climate Clouds also intercept solar radiation
13
Why does it feel cooler on a cloudy day? Sunny Day @ the Beach Cloudy Day @ the Beach
14
Cloud Formation Demonstration I
15
Cloud Formation
16
Cloud Formation Demonstration II
17
Cloud Formation Clouds form in regions of the atmosphere where water vapor is supersaturated. However, the water vapor must condense on aerosol particles to form clouds Aerosols that become a cloud drop Cloud AerosolCloud
18
Why do clouds not form everywhere water vapor exists? Cloud RegionsWater Vapor Regions
19
1 st Indirect Effect AerosolCloud More polluted: Smaller drops Less polluted: Larger drops Fun Fact: The droplets of water or ice in a cloud are about 70 times smaller than the period at the end of this sentence.

1 st Indirect Effect AerosolCloud
21
Why is the crushed ice brighter than the cubed ice?
22
2 nd Indirect Effect AerosolCloud Time
23
Why do clouds get darker right before it rains?
24
What is the overall impact? IPCC, 2001
25
How does this affect us? Climate is a delicate system Predict future climate trends Predict consequences of current actions “ The Day After Tomorrow”
26
Other Aerosol Impacts Acid Rain Acid Rain Anthropogenic (man- made) aerosols Anthropogenic (man- made) aerosols Vegetation Damage Vegetation Damage Ecological system Ecological system Health Respiratory Effects Visibility Smog, Fog, Haze, etc…

Recap Aerosol Climate Direct Effect: -Aerosols absorb and scatter Sun’s Radiation AerosolCloud Indirect Effects: -Clouds need aerosols to form Cloud Climate Clouds Reflect Sunlight From Space Clouds Reflect Sunlight From Space Clouds reflect more and live longer as the number of aerosols increase Clouds reflect more and live longer as the number of aerosols increase
