Study Notes
Meteorology and Oceanography
- VOS (Volunteer Observing Ships) observe meteorological conditions at the surface, in the upper atmosphere, and oceanographic conditions.
Tropical Revolving Storms
- A typical track for a Tropical Revolving Storm (TRS) is westward, then poleward, and finally eastward.
Wind Force
- A severe tropical storm is associated with a wind force of 11-12 on the Beaufort scale.
Fronts and Boundaries
- Polar fronts are boundaries between cold polar air and warm tropical air.
AMVER Program
- Merchant ships are part of the AMVER (Automated Mutual-assistance Vessel Rescue) program.
Weather Patterns
- When a frontal depression approaches from the west, the weather pattern sequence is: warm front, rain, cold front, and clearing.
Monsoon Regions
- The North East monsoon is experienced in the Indian subcontinent.
Cyclone Formation
- Cyclones predominantly originate over warm tropical oceans.
Air Masses
- A large body of air with uniform temperature and relative humidity in a given horizontal plane is called an air mass.
Anticyclones
- An characteristic of an Anticyclone is high pressure and sinking air.
Troughs
- A Trough of low pressure is defined as an elongated area of low pressure.
