2. Recurring Weather

3. Recurring Weather Some weather events happen on a regular basis
These weather events are due to changes in precipitation or temperature that an area has over a period of time

4. Floods and Droughts
Flood – natural occurrence when water spills over the sides of a stream’s banks onto land
Caused by extended periods of above-average precipitation (thunderstorms, hurricanes, or weather fronts that move slowly)

5. Floods and Droughts
Drought – extended periods of below-average rainfall (so there can be rain during a drought, just not much)
Caused by large high-pressure systems in an area for a long period of time

6. Heat Waves Heat Wave – extended period of above-average temperatures
Can result from high-pressure systems in an area for a long time
Few clouds to block the blazing Sun

7. REVIEW: Where is it coolest? Why?
46oC = 115oF 44oC= 111oF 42oC= 108oF 40oC= 104oF 38oC= 100oF 36oC= 97oF 34oC= 93oF 32oC= 90oF 30oC= 86oF
REVIEW: Where is it coolest? Why?

8. Heat Waves Why do people complain about humid days?
Your body is cooled by sweat evaporating off of your skin and taking heat with it
Humid air evaporates less than dry air
The more humid it is, the warmer it feels
“Dry heat” in places like Arizona

9. Heat Waves
Heat Index – how warm the air feels to the human body based on the air temperature and relative humidity

10. Cold Waves Cold Wave – extended period of below-normal temperatures
Can result from high pressure systems of Arctic or continental polar (cP) air masses

11. Cold Waves
Wind blows heat away from the body, so the windier it is, the cooler it feels
Wind Chill – how cold the air feels to the human body based on the air temperature and the wind speed
