Weather Review Battleship!
Air Basics As the temperature of a gas increases what happens to its volume? Increases
Air Basics List the three important properties of air that we discussed. has mass, takes up space, can exert force
Air Basics Define temperature Measurement of speed of molecular movement
Air Basics As you increase altitude through the atmosphere what happens to atmospheric pressure? Decreases
Atmosphere Structure In which atmospheric layer does weather occur? Troposphere
Atmosphere Structure What is the heat source for the troposphere? Heat re-radiating from the Earth’s surface
Atmosphere Structure Why does the stratosphere get warmer as altitude increases? Ozone layer absorbs ultra violet radiation
Atmosphere Structure Why does the temperature in the troposphere decrease with altitude? Farther from the surface which is the heat source
Water Properties What type of molecule is water considered to be? Polar covalent
Water Properties Water sticks to other things is called… Adhesion
Water Properties Water sticks to other water is called… Cohesion
Water Properties Water has a high specific heat, what does that allow water to do? Absorb a lot of thermal energy without changing temperature
Water Properties Water is the only molecule in the known universe to do what as a solid? Float!
Relative Humidity Relative humidity is a measurement of the amount of water in the air in comparison to what? The ability of air to hold water
Relative Humidity What do we call it when air has reached 100% relative humidity? Saturation or dew point
Relative Humidity Warm air has a _____ ability to hold water than cool air. Higher
Relative Humidity If 1 kg of 10 O C air has the ability to hold 7g of water and is currently holding 3.5g, what is the air’s relative humidity? 50% relative humidity
Relative Humidity If 35 O C air contains 7g of water, at what temperature will that air reach dew point (100% relative humidity/saturation)? 10 O C
Cloud Formation Where does air have to be moving in order for there to be cloud formation? Up or rising
Cloud Formation Clouds will form when rising air reaches its _______. Dew point
Cloud Formation This type of cloud is whispy and light and forms high in the troposphere. Cirrus
Cloud Formation This must be present in the atmosphere where water is trying to condense. Without it, no cloud will form. Seeds or condensation nuclei or tiny solid particles
Cloud Formation Why don’t clouds always produce rain? Droplets have to become large enough for gravity to pull them out of the cloud.
Cloud Formation List the four ways to lift air and form clouds. surface heating, orographic lifting, convergence, frontal wedging
Air Masses and Fronts What are the two characteristics we use to describe an air mass. Temperature and moisture (humidity)
Air Masses and Fronts List four different types of air masses. Maritime tropical, maritime polar, continental tropical, continental polar
Air Masses and Fronts What causes air masses to have the characteristics of temperature and humidity that they have? Where they originally come from
Air Masses and Fronts What do we call it when two air masses meet? a front
Air Masses and Fronts What type of weather would you expect to find along a cold front? Stormy weather
Air Masses and Fronts What type of weather would you expect to find along a warm front? Long term steady precipitation
Wind Air always moves from areas of _____ pressure to areas of _____ pressure. High to low
Wind What type of pressure and weather would you expect if air is rising? Low, cloudy
Wind What type of pressure and weather would you expect if air is falling? High, clear
Wind What do we call the actual temperature that humans feel due to wind? Wind chill
Wind What causes a sea breeze? Land warming more then water, rising and causing low pressure, air moves in from high pressure sea
Wind What do chinook winds cause on the leeward side of mountains? Warmer temperatures
Global Winds What causes global winds? Air heating at the equator
Global Winds What is the coriolis effect? The effect that causes the movement of air on earth to curve due to earth’s rotation.
Global Winds What is the jet stream? A river of fast moving high altitude air
Tornadoes and Hurricanes What characteristic of a storm does a hook echo on Doppler radar indicate? Rotation
Tornadoes and Hurricanes What property does the center of a tornado have that causes the “sucking” effect of the tornado? Extreme low pressure
Tornadoes and Hurricanes What is the “fuel” for a growing hurricane? Warm ocean water
Tornadoes and Hurricanes What characteristics do the eye of a hurricane posses? Low pressure, calm
Tornadoes and Hurricanes Why do hurricanes only occur during certain months of the year? Ocean water is only warm enough to spawn hurricanes during certain times.
Thunder and Lightning What charge at the bottom of storm clouds causes lightning to strike the ground? Negative
Thunder and Lightning What causes thunder? Rapidly heating and expanding air
What is Weather?.

Severe Weather --for those who know enough to come in out of the rain.
WINDS Understand the cause of wind and how it affects climate Chapter 4 Chapter 4 Pages Pages
Weather, Winds, and Fronts
Topic VI “Meteorology”
Chapter 16 – Understanding Weather
Weather Dynamics Science 10 G.Burgess Our weather is dependant on the movements of air and water. Light from the sun heats the Earth and oceans.
Earth’s Weather and Climate
Do Now 1. What Factors influence air temperature? 2. What factors influence air pressure? 3. How does air move in and around a low pressure system? 4.
Air Pressure: The weight of the air in the atmosphere pressing down. At sea level the air pressure is mb (millibars) = 1 atmosphere 1 atmosphere.
Section 17.1 Notes Weather changes as air masses move.
Chapter 2 Section 3 Winds.
Warm Up 3/14 Which gas is most important for understanding atmospheric processes? a. water vapor c. carbon dioxide b. oxygen d. ozone What is true.
Heating of Land and Water Land Heats up faster and Cools down faster than water.
