Study for Extreme Heat

Question 1

When humidity makes an area feel warmer, is this because evaporation is more or less effective?

Answer 1

Less Effective

Question 2

What does the heat index measure?

Answer 2

What temperature feels like for human in regards to humidity levels and air temperature.

Question 3

What can keep nights warmer?

Answer 3

Greenhouse effect of Water Vapor

Question 4

How does warmer nighttime heat affect human health?

Answer 4

It affects/increases their mortality, morbidity, and infrastructure rates.

Question 5

How does Dry Heat work?

Answer 5

Deserts heat up much faster during the day and cool down at night.

Dry Climates -> Low Average Temperature -> Greater Water Vapor -> Lack of Greenhouse Effect (No Cooling Effect)

Question 6

What chases Urban Heat Island effect?

Answer 6

• Longwave Radiation Blocked By Buildings
• Asphalt/Concrete Absorbing Solar Radiation
• No Vegetation (Less Evaporation)
• Combustion from Cars and Buildings Release Heat

Question 7

What is a Jet Stream?

Answer 7

A band of strong winds blowing west and east with high altitudes, circling the globes

Question 8

Future of Extreme Heat

Answer 8

More likely got extremes; less likely cold extremes

Many places experience increase in heat index.
- More greenhouse gases -> Hotter nights in locations that don’t dry out
