Each Mass is described with a Temperature & Moisture Ex: Hot / Dry Ex: Cold / Moist
Air mass that forms over tropics is _______ than one that forms over the northern regions. Air mass that forms over water is more ______ than one that forms over dry land.
Recall: Winds blow from an area of ______ pressure to an area of _____ pressure! (high to low)
Associated with fair / nice / SUNNY/ clear weather because the high pressure does not allow air to rise and form clouds Hint: Think of High 5= Good Weather Or Thumbs UP!
Associated with cloudy / rainy weather because the warm air rises and forms clouds Thumbs Down
Lines on a weather map that connect equal areas of pressure. The lines show what type of wind may occur Lines that are close= Strong/Fast Winds Lines that are far= Little to No Wind
It is usually cloudy and stormy at a front 4 Types ◦ Cold ◦ Warm ◦ Occluded ◦ Stationary
In your journals, identify these symbols
Divide your paper into four equal sections Read the FRONTS section on page 127 & 128 Label each section with the 4 fronts: ◦ Cold Front, Warm Front, Occluded Front, Stationary Front Describe what happens at each front & what type of weather occurs Draw a picture of each front & use Red & Blue colored pencils to add color. INCLUDE THE SYMBOL OF THE FRONT!!!!!!
Fronts move in the direction they are headed! Tips: The blue triangles on a cold front= think of icicle Q: What types of temperatures are left after a cold front moves through? Q: What direction is this cold front moving?
Hint: The half circles on a warm front= think of the sun Q: What types of temperature are left after a warm front moves through? Q: What direction is this warm front moving?
Neither cold nor warm air advances. Hint: Think of the line of scrimmage in a football game when both teams equally push against each other OR a Stationary Bike!
Hint: The 2 C’s in oCCluded for 2 cold air masses. Cold air masses close out the warm air from the surface. The only front that includes ____ air masses. ( How many air masses are involved?)
