Meteorology: the study of Earth’s atmosphere Meteor – In ancient Greek – meant “High in the air” Current meanings still apply Meteor – astronomical entity.

 Climate is the characteristic weather that prevails from season to season and year to year.

Weather Review. Air Masses Air Mass – A large body of air through which temperature and moisture are the same. Types 1. Continental – formed over land.

Meteorology Review Chapters Question – What instrument do you use to measure atmospheric pressure? Answer – Barometer.

Pressure Systems Low pressure: an area where the atmospheric pressure is lower than the surrounding area Air rises then it cools and condenses Weather:

Warm air near the Earth’s surface rises and then cools as it goes back up. Convection happens on a global scale in the atmosphere and causes global winds,

Severe Weather Week 6

Questions for Discussion Which types of severe weather risk are you willing to live with? Why? What level of risk from severe weather is acceptable to you? (How would you know if the severe weather risk was assessed accurately?) What should be done by people and communities to prepare for severe weather hazards and prevent catastrophe? Which types of severe weather risk are you willing to live with? Why? What level of risk from severe weather is acceptable to you? (How would you know if the severe weather risk was assessed accurately?) What should be done by people and communities to prepare for severe weather hazards and prevent catastrophe?

Other Things to Consider What factors influence the impact of severe weather? How do severe weather hazards vary from place to place? Why? The five fundamental concepts form Chapter 1 What factors influence the impact of severe weather? How do severe weather hazards vary from place to place? Why?

How it works Energy transfer radiation (light>surface>air) convection (air currents) role of water Energy transfer radiation (light>surface>air) convection (air currents) role of water Structure of the atmosphere

Atmospheric Circulation Heat energy moves from equator to poles Creates high & low pressure systems Deflected by coriolis effect
