Which map shows the two correctly labeled air masses that frequently
converge in the central plains to cause tornadoes?
Typical Northern Hemisphere Cyclone
(Cyclone = Low Pressure System)
Fronts only occur in
air masses converge.
, where
•Cold air behind
•Moves quickly
•Deep/thick clouds = heavy storms (thunderstorms)
•Warm air behind
•Moves slowly
•Long thin clouds = light steady precipitation

This satellite image shows cloud patterns associated with weather
fronts over the United States on a certain day. Nebraska (NE) and New
York (NY) are labeled.
(1) cold front
(3) stationary front
(2) warm front
(4) occluded front
Base your answers to questions 57 through 59 on the cross section
below, which shows 2 weather fronts moving across N Y State. Lines X
and Y represent frontal boundaries. The large arrows show the general
direction the air masses are moving. The smaller arrows show the
general direction warm, moist air is moving over the frontal boundaries.
