INTRODUCTION TO EARTH SCIENCE
ESCI 121
Fall 2010
Section 05

DAILY OBJECTIVES
IMPORTANT UPDATES:

w An assignment is due one week from today (Tuesday, Dec. 7, 2010).

w All weather-tracking maps are due no later than Tuesday, Dec. 7, 2010.

w We will not have class this Thursday, Dec. 2.  (I will be in Washington DC meeting with the USDA.)

By the end of today's class, you should be able to do the following:

WEATHER

w   Explain the difference between climate and weather.

Air Masses

w   Explain what humidity is and tell how humidity measurements are expressed.

w   Explain what an air mass is.

w   Explain how moisture content and temperature of an air mass affect its density.

w   Describe
continental polar (cP), maritime tropical (mT), continental Arctic, (cA), and other air masses that affect the continental United States.  (See http://okfirst.mesonet.org/train/meteorology/AirMasses.html and http://www.usatoday.com/weather/tg/wamsorce/wamsorce.htm.)

Clouds

w   Explain what the term dew point means.

w   List the steps that lead to the formation of a cloud.

w   Explain the terms condensation and condensation nuclei as they relate to cloud formation.

w   Describe the characteristics of cirrus, cumulus, and stratus clouds.  See http://asd-www.larc.nasa.gov/SCOOL/tutorial/clouds/cloudtypes.swf for more information.

w  Tell what cumulonimbus and nimbostratus clouds have that ordinary cumulus and stratus clouds don't. 

Fronts and Precipitation

w   Explain what a front is.

w
  Explain the processes that lead to orographic ("relief"), convective, and frontal precipitation, and sketch a diagram illustrating each one.  See http://www.curriculumbits.com/prodimages/details/geography/types-of-rainfall.html .

w   Make a sketch of a warm front and use it to explain why precipitation is associated with these fronts. 

w   Make a sketch of a cold front and use it to explain why precipitation is associated with these fronts. 

Barometric Pressure

w  
Explain the meaning of air pressure / barometric pressure.

w   Describe the characteristics and movement of air in a high pressure zone and a low pressure zone.
