WHAT IS A STORM?Weather is not always the same. You can tell so by looking outside or find out about the weather by watching weather forecasts on the TV, Internet, Mobile phone apps, Radio and so on.

A STORM is when weather gets:

RAIN

RAIN is drops of water that fall from clouds in the sky. Rain is very

important because it provides fresh water for us to drink and for plants

to grow.But lots of rain can cause hazards,

including flooding(see the separate unit on

FLOODING)


RAINRAIN can be measured by using aRAIN GAUGE

Make your own RAIN GAUGEand find out how much rain falls where you live


HAIL

HAIL is when round or irregularly shaped pieces of ice fall from the

sky. Most hailstones are less than 25 mm in diameter, but some can be

larger. Large hailstones can cause damage to property or crops in the fields. Hailstones can also hurt you when

they hit your skin – STAY INSIDE DURING A HAILSTORM!


SLEET

SLEET is rain drops that freeze into ice pellets before they reach the

groundSleet does not usually stick

to objectse-Learning for the Prevention, Preparedness and Response to Natural Disasters

SNOW

SNOW is formed by a number of ice crystals joining

together.No two snowflakes are ever the same


BLIZZARDSBLIZZARDS happen when there is heavy snow and strong winds.Blizzards are very cold and can be dangerous.It is difficult to see and you can easily get lost during a blizzard.


SNOW DRIFTS

During heavy snow there may be snow

drifts.These are deep areas

of snow caused by the wind that blows

snow into deep piles.Snow drifts can be

several metres deep.


STORM SURGES

STORM SURGES create large waves.The highest waves wash away sand dunes, batter sea walls and break

over coastal defences causing FLOODING. e-Learning for the Prevention, Preparedness and Response to Natural Disasters

THUNDER AND LIGHTNING THUNDER is a loud cracking or rumbling noise in the sky.



LIGHTNING is a sudden flash of light which can be in the shape of sheet or fork.



LIGHTNING is a sudden flash of light which can be in the shape of sheet or fork.

LIGHTNING IS VERY DANGEROUS –If you are struck by lightning you are electrocuted and could be killed


Thunder may also occur together with other types of stormy weather

causing the following: THUNDERSLEET – there is thunder and lightning together with sleet or freezing rain

HURRICANES HURRICANES are large tropical storms with extremely strong winds- more than 60 mph- can last more than a

week

HURRICANES gather heat and energy through contact with warm ocean waters

HURRICANE force winds can also occur in Europe and cause lots of damage.


WHY ARE STORMS DANGEROUS?

STORMS CAN CAUSE FLOODING: Heavy rain may

cause the water level to rise

Link to the FLOODING unit





Drains can be blocked during storms and water has nowhere to go






Drains can be blocked during storms and water has nowhere to go

Melting snow can sometimes cause flooding after the storm has passed



DIFFICULT TO MOVE AROUND: Slippery paths and

roads




roads Snow can block

paths. and roads, especially if there are large snow drifts.




roads Snow can block

paths. and roads, especially if there are large snow drifts.

Cars, trains and buses may not be able to travel or may get stuck.





STORMS CAN CAUSE DAMAGE: High winds can

damage houses and knock down trees





Trees may fall on people or cars






Fallen trees may block paths and roads






Fallen trees may block paths and roads

Landslides and mudslides may happen

PRACTICAL EXERCISES1. WORD SEARCH – STORM WORDS

2. MAKE YOUR OWN RAIN GAUGE

3. MAKE YOUR OWN WIND VANE

4. MAKE YOUR OWN THERMOMETER BOX


Hurricanes are large tropical storms that have extremely strong winds of more than 60 miles per hour and can be hundreds of miles across. Some hurricanes will last for more than a week. Hurricanes gather heat and energy through contact with warm ocean waters and it is for this reason that they are referred to as tropical storms. However, hurricane force winds can occur in Europe and have caused significant damage in the past.

In the Atlantic Ocean, Gulf of Mexico and the Eastern Pacific Ocean they are called HURRICANES

FACTS AND FIGURES Hurricanes occur every year and there may be multiple hurricanes at once. The World Meteorological Organization has developed a list of names to help meteorologists, researchers, emergency workers, ships’ captains and others to communicate effectively about specific hurricanes. Names have been given to Hurricanes in the Atlantic for more than 100 years. If a named hurricane causes death and destruction then that name is retired from use.
