Weather class chapter 7 quiz
1.
The difference between cyclonic and anti-cyclonic flow, clockwise and
counterclockwise flows
Cyclonic flow: large red L indicates centers of low pressure, wind travels into and around a cyclone
counterclockwise in the northern hemisphere
Anti-cyclonic flow: large blue H indicates centers of high pressure, wind travels out of and around an
anticyclone clockwise in northern hemisphere
Clockwise flow: anticyclone, northern
Counterclockwise flow: cyclone, northern
2.
Gradient wind and conditions under which it occurs in the atmosphere
A wind that blows at a constant speed parallel to curved isobars above the level of frictional influence
3.
Zonal and meridional flows
Zonal flow : winds blowing in a west to east direction
Meridional flow : a wind flow pattern in which the wind flows in large looping meanders, following a
north-south trajectory
4
. Lines connecting equal values of weather elements – isobars, isotherms , etc..
Closely spaced= strong pressure gradient
