AND
WEATHER
LUISA CAMBERO

2. There are four seasons in a year:
spring, summer, autumn and
winter.
We have different weather in
different seasons. In Spain is hot
and sunny in summer.
SPRING:
March, April and May
SUMMER:
June, July and August.
AUTUMN:
September, October and November
WINTER:
December, January and February.

3. INSTRUMENTS
We use different instuments to measure the weather
THERMOMETER
measures the temperature
WEATHER VANE
points the wind is coming from.
RAIN GAUGE
Measures how much
rain falls.

4. WIND IS MOVING
AIR
A gentle wind is BREEZE
A strong wind is called a GALE
HURRICANES are very strong winds.

5. WATER CYCLE
The sun heats water in oceans, seas and
rivers.
Water evaporates. It is EVAPORATION
Water flows back to the oceans, seas and
rivers
Water vapor forms clouds. Clouds are
made of lots of tiny water droplets.
It is CONDENSATION.
Water falls from clouds as a rain, snow,
hail or sleet.
It is PRECIPITATION.

6. PRECIPITATION IS WATER THAT FALLS
FROM THE CLOUDS.
IT CAN BE SOLID OR LIQUID
Precipitation
normally falls as
a rain
Precipitations
can be snow
Precipitations
can be hail
Precipitations
can be sleet

7. WEATHER

TO SEASON, BUT
IT ALSO CHANGES
DAY BY DAY
 We use symbols to represent the different
types of weather on weather maps.
 Cloudy. Foggy. Rainy. Stormy.
 Gale. Sleet. Hail Breeze
snowy sunny

8. We need to be prepared for different types of weather.
We wear warm clothes
when it is cold
We wear cool clothes
