I have a meteorology test on weather maps, and I'm having a bit of trouble on some things...
If anybody knows how to do any of these things explain or provide a link explaining.. Thank you.
* Identifying air masses
* Labeling fonts
* Drawing cross sections of fronts
* Finding path of jet stream
* Labeling trough and axis
* Labeling highs and lows
* Identifying areas of greater and lesser wind speeds.

Very general guidance...
* Identifying air masses
Dew points analysis can be used as a 1st approximation to identify air masses.
Mid-60s and above: tropical
40s and 50s: polar
L30s and below: arctic
If the air mass originated over land - continental; over water - maritime
* Labeling fonts
Cold fronts have blue teeth
Warm fronts have red semi-circles
Occluded fronts have purple teeth and semi-circles
* Drawing cross sections of fronts
Draw a line perpendicular to the front and plot the weather (wind, cloud cover, cloud type, precipitation) observed on either side.
* Finding path of jet stream
Jet stream is found about five to seven miles above the surface flowing from west-to-east.
The strongest winds are located where the horizontal change in temperature is the greatest.
* Labeling trough and axis
Connect the points with local minimums in barometric pressure and a sharp wind shifts are found and there's no sharp temperature contrast
.
* Labeling highs and lows
Blue H where the highest pressure is found; Red L where the lowest pressure is found.
* Identifying areas of greater and lesser wind speeds.
Higher wind speeds are found where the isobars are closest together
Lower wind speeds are found where the isobars are farthest apart.

look up surface analysis. Fronts will be located near a temperature gradient (the leading edge of it, with the cold air ahead in a warm front, and the cold air behind it in a cold front. There will also be a sudden wind change. On the cold side of a cold front, winds will be from the north west , on the other side of the cold front. winds will be from the southwest or west. Station plots will also indicate overcast conditions near a front. Also, the fronts will both be associated with a "kink" or small trough in the isobars. The cold front's kink in the isobars will be sharper. the warm front will likely be harder to locate than the cold front.
You draw the low pressure center at approximately the location where the wind circulation is centered on, and moving counterclockwise around.
