depressions, anticyclones) & their interaction with humans
Unit C : Hurricanes and their impact on people & property
A (i) Temperature
• Global energy balance
• The atmosphere is fluid. Transfer of energy is necessary because of uneven heating of globe.
• Vertical & horizontal heat transfer
• Heat is transferred vertically by air movement and horizontally by wind and ocean currents.
Meteorology is the study of atmospheric
phenomena (weather & climate). Vertical structure of
atmosphere
The atmosphere is an envelope of transparent, odourless gases held to the earth by gravitational attraction. Most of our weather happens in the first 16km ( it extends to 1000km).
