Slide1

Weather and Water

Investigation 1

What is weather?Slide2

What is Weather?

Well?

Write in your journal what weather is.

What factors would you need to consider if you were going to describe or forecast weather?

Have one person from your table login

to the computer.Slide3

Part 1

Into the WeatherSlide4

Today’s Weather

Is today’s weather normal for this time of year? If not, what weather would you expect?

Is this the kind of weather you would expect to happen everywhere on Earth today?

Australia

Brazil

RussiaSlide5

Things that fall from the sky

What are some things that might normally fall from the sky?

What do we call that stuff?

Video Clip

What surprised you about the weather shown in the video?

Weather that is dangerous or causes damage is called severe weather. Describe any severe weather you have experienced.

What other types of severe weather have you heard or read about?Slide6

Hurricanes

Video Clip

What is a hurricane?

What conditions are necessary for a hurricane to form?

What kinds of damage occur during hurricanes?

What are some things people have done to try to lessen hurricane damage?

Where have some of the most devastating hurricanes occurred and when?

How do meteorologists know when a hurricane is coming or where it might strike land?Slide7

What is a hurricane?

An area of low pressure into which air rushes, creating powerful winds that spiral around a central eye.

The wind blows at least 75 mph or 120 km/h.Slide8

What conditions are necessary for a hurricane to form?

An ocean with water temperature at 81 degrees (27 degrees Celsius) or higher

An area of low pressureSlide9

What kinds of damage occur during hurricanes?

Wind damage

Water damage

Property damage

FloodingSlide10

What are some things people have done to try to lessen hurricane damage?

Moved entire cities inland in Belize

Improved hurricane forecasts

Help people prepare for securing property or evacuating

Built seawalls in Galveston

Built houses on stilts

Tried to fix levies in New OrleansSlide11

Where have been some of the most devastating hurricanes occurred and when?

Galveston 1900

Belize – Hurricane Hattie – 1961

Galveston – Hurricane Alecia – 1983

Caribbean Islands and Yucatan Peninsula – Hurricane Gilbert – 1988

Bangladesh 1991

Florida – Hurricane Andrew – 1992

Gulf Coast – Hurricane Katrina - 2005Slide12

How do meteorologists know when a hurricane is coming and where it might strike land?

Ground observations

Aircraft observations

Satellite imagesSlide13

Video Reflection

The two video segments gave us some things to think about and may have raised some questions. You might have some other questions about weather that we experience where we live.

In your journal title a page – Weather Questions. Write down three to four questions.

Share with your table – write down any more questions you come up with.Slide14

Question Categories

Write your questions on a stick ‘

em

One question per stick ‘

em

Put your question under one of the following categories.

Weather conditions

Local weather

Severe weather

Definitions

Other?Slide15

Hurricane Homework

Bring in an article, picture, etc of current hurricane information happening right now.

Hurricane Dean!Slide16

Meteorology

What do you think of when you see that word?

Meteorology

is the scientific study of Earth’s weather.

A person who studies the causes and effects of weather is a

meteorologist

.

The word literally means study of meteors.Slide17

Huh?

What do meteors have to do with weather?

In ancient Greece, anything that fell from the sky was considered a meteor, whether it was what we know as a meteor today, rain, snow or hail.

Today meteorology includes only the study of weather.

Planetary scientists study meteors now.

Some meteorologists study weather to make

forecasts

to let people know what kind of weather to expect in the next day or week.

Name some of our local meteorologists on the Seattle TV stations.Slide18

Using Weather Forecasts

In your journal, write down why people listen or look at forecasts. What kind of decisions are made based on weather forecasts?

How to dress

Travel plans – especially air

Health considerations – allergies, colds,

flus

Business considerations such as seasonal goods like umbrellas, snow gear, swimsuits

Vacation or recreation plans like camping, sailing or picnics

Agriculture or gardening plans, spring planting, harvestingSlide19

Naming Hurricanes

Read pg. 3-4 in the book

In your journal write down the old rules for naming hurricanes,

And today’s rules for naming hurricanes.

What happened to naming hurricanes in 1978?

What happens to the names of the most severe storms?

When do storms get their name?Slide20

Homework

Bring in a weather report from a

Newspaper

Online source

Other

We will be using these reports in class tomorrow

It would be bad if you forget.

Very, very badSlide21

Part Two

Local WeatherSlide22

Your Weather Report

In your journal write down your version of today’s weather report for the weather right now. Today’s weather is…

Share your weather report with your table.

Use your highlighter to highlight any common words in your weather reports.

Write your table’s common weather words on your whiteboard.Slide23

Weather Reports

Pull out the weather report you obtained for your homework.

Answer the following questions in your journal:

What types of information are included in your weather report?

What was the source for your weather report?

How does this weather report compare to the report you wrote.Slide24

Today’s Weather Report

Weather Underground rocks

Write down the following in your journal, then record the data from Weather Underground

Temperature – how hot or cold the air is

Humidity – the amount of water vapor in the air

Wind direction – the compass direction from which the wind is coming

Pressure – the force of the air pushing in all directions

Visibility – the distance one can see through the airSlide25

Weather Underground

Here’s the report from

Weather Underground

for us today.

As you look at this page, write down what other information it includes other than what we already wrote downSlide26

Weather Tools

Thermometer – temperature

Barometer – air pressure

Hygrometer – humidity

Anemometer – wind speed

Wind vane – wind direction

Open your books to page 5 and follow along as we go through these toolsSlide27

Class Weather Chart

What do you think visibility means?

What weather factors might limit visibility?

How can we determine what the visibility is?

What additional information might be included in the column headed “Other Observations”?Slide28

Daily Measurements

Tables will take turns collecting weather data and recording it on the class weather chart.

How to do this:

Go outside to the tables

Carefully take out the tools

The anemometer and compass should be used together to determine wind speed and direction.Slide29

Scientific Measurements

Temperature in Celsius

Pressure in

millibars

(

mb

)

Humidity in percent

Wind speed in km/h

Wind direction is the compass direction form which the wind is comingSlide30

The Weather Machine Video

Take notes in your journal of what drives weather in our world.Slide31

Storm Chasers

Storm chasers are people who intentionally try to get in the path of severe weather. As you watch this segment, try to figure out why they do such apparently foolish things.

What kind of weather do storm chasers study?

Why do storm chasers engage in such dangerous activities?

What weather factors do storm chasers measure?

Write down three things you already knew about weather.

Write down three things you didn’t know about weather.Slide32

World Weather

You are going to collect weather data for any city in the world you want to.

You are going to make your own data sheets.

You can do your data sheets by hand or on the computer.

Write down what city you want to track.

What kind of data should you collect?

How long should we collect data?Slide33
