Answer:
- Cold front → blue line/triangles
- Warm front → red line/semicircles
- Occluded front → lines with triangles and semicircles
- Low pressure → L
- High pressure → H
- Strong winds, cloudless → White key
- Strong winds, very cloudy → Black filled key
Step-by-step explanation:
ISOBARS:
These are lines that join points of similar pressure and indicate atmospheric pressure for different regions. If lines are very close to each other, means that there will be bad weather. This is because, at a short distance, pressure values change, meaning atmospheric instability.
PRESSURE ZONES:
Isobars indicate the speed and direction of winds. Winds move from high atmospheric pressure areas to lower atmospheric pressure areas. When isobars are placed as small circles, there is a letter indicating the pressure center. It can be either high pressure symbolized with an H, or low pressure symbolized with an L.
- High-pressure zones, H, represent anticyclones and are associated with good weather.
- Low-pressure zones, L, represent cyclones and are associated with bad weather. The closer the lines are to each other, the stronger will be the winds.
FRONT TYPES:
There are different types of fronts, which can be represented with different symbols.
- Cold front: In weather maps, these are represented with blue lines with triangles indicating the direction of the wind movements.
- Warm front: In weather maps, these are represented with red lines with semicircles indicating the direction of the wind movements.
- Occluded front: It can be warm or cold. These are represented with purple lines with triangles and semicircles indicating the direction of the wind movements.
CLOUD COVER / WIND SPEED:
Indicated as a key figure on the map.
- Circle: Represents the percentage of cloud cover. The clouder it is, the more black will be the circle.
- Stick: Represents the wind speed. The stick can have lines indicating the degree of speed → stick with no transversal line indicates 1-4 mph, one line means 5-8 mph, two lines 9-14 mph. And so on.
