Study Notes
Air Masses
- Continental tropical air mass is characterized by low relative humidity and high air temperature.
- Maritime Tropical (mT) air mass has high humidity and high air temperature.
Geographic Origin of Air Masses
- Air masses forming over Mexico, specifically, can be classified as continental tropical due to their origin.
Weather Maps
- Understanding symbols is critical: Symbol 'a' represents the frontal boundary at line AB.
- Identifying fronts and their movement direction is essential; map 'a' correctly indicates these.
Atmospheric Conditions
- Precipitation occurs at location 'b' on the weather map.
- Atmospheric conditions influencing location 'c' are described by symbol 'd'.
Air Temperature and Humidity Comparison
- The mT air mass is distinguished from the cP air mass by being warmer and more humid.
Surface Winds and Low Pressure
- Surface winds around a low pressure area generally move in a counterclockwise and inward direction.
Frontal Boundaries
- Cross section 'c' accurately represents the frontal boundary (fb) and air movement between locations 'c' and 'd'.
- Cross section 'c' also best represents fronts and air movements along line XY on the weather map.
