Study Guide and Practice Quiz for Quiz on Chapter 3: Weather Patterns – Part 1
Quiz on Tuesday, March 22 or Wednesday, March 23, 2016
Study Materials:
Chapter 3 of the text: Section 1 (Air Masses and Fronts)
“Air Masses” and “Fronts” notes sheets
“Modeling a Front” lab
“Notes on Cyclones and Anticyclones” to be given out
Study Topics: Section 3-1, Section 3-2, and Weather Maps on page 102 in section 3-4
• Know the definition of an air mass, the characteristics of the main types of air masses, and how air
masses are named using combinations of the terms polar, tropical, continental, maritime and what
those terms mean
• Know which two types of air masses affect NJ’s weather the most.
• Know the definition of a front and why, how and where clouds form at fronts.
• Identify cold and warm fronts by definition, description, and picture. Know the possible types of
weather changes with each. Know how symbol on a weather map shows which way they move.
• Know that wind tends to blow from high to low pressure, but is deflected by the Coriolis effect.
• Compare cyclones to anticyclones (CCW or CW rotation direction in each hemisphere, center of high
or low pressure, wind direction spirals inward towards center or outward away from center, rising or
sinking air, clouds or clear skies, whether they occur in relation to fronts).
