What is a Heat Wave?

According to the World Meteorological Organization, a Heat Wave occurs when the daily maximum temperature of 5 consecutive days exceeds average maximum temperature by 5 degrees Celsius. During a heat wave, the weather is excessively hot and also highly humid. Heat Waves usually occur in oceanic countries.

How are Heat Waves formed?

Heat waves are formed when high pressure in the upper atmosphere strengthens and remains in a particular region for days together. They are common in summer as jet streams follow the sun. This high-pressure traps highly humid warm air under it. The air warms oceanic winds in the earth forming heat waves.
