Question 5 of 5
5. Question
Consider the following statements.
- Heat waves begin when high pressure in the atmosphere moves in and pushes warm air toward the ground.
- A hot spell is labelled as a ‘Heat Wave’ only when temperatures are above the historical average in an area for more than one week.
- When heat waves occur, the wind and cloud cover are minimised, which makes the air hotter.
How many of the above statements is/are correct?
Correct
Solution: b)
Statement 2 is incorrect.
Temperatures must be above the historical average in an area for two or more days before the label “heat wave” is applied to a hot spell. But the definition can vary by region;
Heat waves begin when high pressure in the atmosphere moves in and pushes warm air toward the ground. That air warms up further as it is compressed, and we begin to feel a lot hotter.
The high-pressure system pressing down on the ground expands vertically, forcing other weather systems to change course. It even minimizes wind and cloud cover, making the air more stifling. This is also why a heat wave parks itself over an area for several days or longer.
