Question

What did the author mean when he said that summer storms can “snap” a heat wave? Why was the word snap used?

Answer 1

Answer:

Sweltering summer heat waves are on the rise across the Northern Hemisphere. The rise is being driven by changes in the atmosphere spurred by a warming Arctic, new research shows.

Scientists came to that conclusion after examining 35 years of weather data. They spotted a decline in the strength of summer storms. These storms bring welcome relief to northern continents in the form of cool, moist air. Wind pattern changes brought on by the rapidly warming Arctic weakened summer storms. The researchers described their findings online March 13 in Science.
