Weather Phenomena SOL 4.6 Follows along with Interactive Notebook notes

2 Temperature Weather Includes: Precipitation Wind

3 Weather Instruments (Tools)
Temperature- the measure of the amount of heat energy in the atmosphere Measured using a THERMOMETER

4 Additional Weather Instruments
Wind Speed is measured using an ANEMOMETER Wind Direction is measured using a WEATHER VAIN.

5 Additional Weather Instruments
A RAIN GAUGE is used to measure the amount of precipitation.

6 Precipitation Includes:
Rain Snow Formed by ice crystals*

7 More types of Precipitation:
Mixture of snow and rain Sleet Hail Formed by ice crystals*

8 Air Masses and Fronts Air Masses: formed when air in the atmosphere is heated at the equator and cooled at the poles. Fronts: formed when two air masses of different temperatures and humidity* bump into each other. *Humidity is the amount of water vapor in the air.

9 Types of Fronts Cold front Warm front
Cold air mass pushes into a warm air mass. Warm air mass pushes into a cold air mass.

10 Additional Weather Tools
Air pressure is the result of the mass/weight of the air and temperature pushing on its surroundings. (atmospheric pressure) Measured using a BAROMETER

11 Do weather forecasters use air pressure to predict the weather?
High pressure areas are formed when air is cooled. Low pressure is formed when air is warmed. Weather associated with low pressure areas are: clouds, rain, and wind.

12 Thunderstorms Storms Tornadoes Hurricanes

13 Most common in Virginia, but when?
Thunderstorms Strong winds, heavy rain, thunder, and lightning. Most common in Virginia, but when? How are they formed?

14 Hurricanes Largest Storm on Earth! Form over warm water
How do they begin? What are some of the characteristics of a hurricane? Hurricanes

15 What types of wind speed and what can they do?
Tornados Column of warm air begins to spin upward forming a funnel cloud. What types of wind speed and what can they do?

16 CLOUDS Clouds are formed when warm air carrying water vapor rises from the Earth and the water vapor cools down and connect to each other. Are all clouds the same?

17 Cumulus Fluffy, white clouds with flat bottoms. Cumulus clouds usually indicate fair weather. (Middle) Cotton balls Resemble?

18 Cirrus Feathery, wispy, clouds; associated with fair weather. They often indicate that rain or snow will fall within hours. (High) Tiny ice crystals instead of water vapor Made from?

19 Stratus Flat, smooth, gray clouds that blanket/cover the whole sky. (low) Light rain and drizzle What type of weather?

20 Cumulo-nimbus Foul weather storm clouds that bring heavy rains and thunderstorms. Cumulus clouds joining together How are they formed?

21 Spot the cloud! Low and flat ….. Stratus

22 Spot the cloud! Middle level, fluffy ….. Cumulus

23 Spot the cloud! High level, wispy ….. Cirrus

24 Spot the cloud! Rain bearing, storm clouds ….. Cumulo-Nimbus

25 Let’s Review  It’s time to play the… Flyswatter Game

26 Cirrus Clouds Cold Front Wind/Weather Vane Thermometer Hurricane
High pressure Snow Air Masses Cumulous Clouds Low pressure Precipitation Barometer Sleet Cumulo-nimbus Clouds Hail Rain Gauge Warm Front Air pressure Clouds Thunderstorm Tornado Anemometer Stratus Clouds Weather Meteorologists Teacher should use the essential knowledge from the 4th grade science curriculum framework to ask questions.

27 The ABC’s of Weather Draw a letter from the bag. Share a word or phrase that begins with the letter to summarize weather. Tara Moore, Elementary Lead Science Teacher Suffolk Public Schools October 2005 Some cloud slides adapted from John Harris, Radley College, UK
