WEATHER FORECAST
TODAY'S NATIONAL WEATHER FORECAST
Watch the video on “Daily Weather Report”.
Transcribe the text of the video into your exercise book and translate into italian.
• Weather describes the state of
the air, or atmosphere, on our
planet, in a particular time and
place.
Translate the following words:
• Weather is different in different
parts of the world and changes every
minutes, hours, days and weeks.
• It’s constantly changing.
Temperatures …………
Sunny …………
Degrees …………
Showers …………
Wind …………
Stormy …………
Cloudy …………
Weather …………
Spring …………
Rain …………
Cool …………
Warm …………
Forecast…………
Watch the video, listen and fill in the gaps with the
words in the box:
• Today is a ………… day in Sicily, Sardinia, in the north of Italy and
along the Tyrrhenian coast.
• It's partly cloudy and stormy, with ………… and temperatures
between fourteen and nineteen ………… Celsius.
• What’s the ………… like today?
• Tonight the ………… will be thirteen degrees Celsius.
• It’s a ………… day with heavy showers and it's very humid.
WEATHER - TEMPERATURES - SUNNY - STORMY - SHOWERS -
DEGREES
Let’s play! What’s the
weather like?
• Weather and climate are not the
same things!
• Climate describes the usual weather
of a place over time.
Watch the video, listen and select with a cross the right weather conditions. •What’s the season in Italy at the moment?……………… •The weather in Faiano is not ............ (bad - cold - cool - warm - hot - lovely). Temperature now: ............ Weather situation morning: •The weather in Rome is ............ (bad - cold - cool - warm - hot - lovely). Temperature now: ............ Weather situation afternoon: •The weather in Florence is ............ (bad - cold - cool - warm - hot - lovely). Temperature now: ............ •Weather situation morning:
Let’s look at the
spidergram on weather.
Air is everywhere
• The air is invisible and we forget it,
but air is everywhere!
• Air is a mixture of gases, principally
nitrogen and oxygen, and varying
amounts of water vapor and carbon
dioxide.
• Air occupies its own space, it has
its own weight and it moves with
the wind.
• Air forms the atmosphere that
surrounds the Earth.
Let’s look at the
spidergram on the air!
• Read the text, then complete the sentences:
• Air is made up of gases, principally ………………
and ……………….
• Air also contains water ……………… and
……………… dioxide.
• Air moves with the ……………….
• Air has its own ……………… and ……………….
• The ……………… surrounds the Earth.
TROPOSPHERE
STRATOSPHERE
MESOSPHERE
THERMOSPHERE
EXOSPHERE
Atmosphere
• Earth's atmosphere has five
layers.
• Each layer has a different
temperature, size and height
above sea level.
Let’s play! The
atmosphere.
• Weather occurs in the
troposphere.
• There are many different
factors that can change
atmospheric conditions and
weather in a certain area.

Three factors can change air pressure!
• Air pressure is the weight of
the air molecules on a
surface.
• Barometers measure air
pressure.
Let’s look at the
spidergram on the air pressure!
LET'S USE THE
ACRONYM… H. A. T.
• HUMIDITY
• ALTITUDE
• TEMPERATURE
Air pressure
Let’s look at the
spidergram on
atmospheric phenomena!
WHAT’S THE WEATHER LIKE?
Changes in air pressure cause changes in the weather!
TEMPERATURE HUMIDITY PRESSURE WEATHER
COLD DRY HIGH GOOD
WARM WET LOW BAD
LOW
HIGH HIGH
LOW HIGH
LOW
Let’s play! Air
pressure.
• The heat of the Sun warms the
Earth’s surface.
• The air gets warm.
• Warm air is light and it rises.
• Air pressure is low.
Why does the wind blow?
• Warm air molecules are
farther apart and less dense.
• The air gets cool.
• Cold air is heavy and sinks.
• Air pressure is high.
• Cold air replaces the warm air
and warm air replaces cold
air.
• The movement of the air
causes wind.
• Cold air molecules are close
together and more dense.
Why does the wind blow?
Wind is caused by changes in air pressure. Wind is a mass of air moving from a high pressure-area to a low-pressure area.
High pressure
Low pressure
WIND
The air will blow from high to low!
Why does the wind blow?
Low pressure causes warm air rising, cooling, and forming clouds.
BAD WEATHER
High pressure causes cold air to sink, warm up, preventing clouds from forming.
GOOD WEATHER
The weather forecast is based on data from atmospheric pressure. Let’s play!
Wind and Air
Pressure.
This is a Doppler map. Black fine lines are isobars. Isobar is a closed line drawn on a weather map that connects points with the same atmospheric pressure.
H = HIGH PRESSURE: A high pressure system is a mass of cool, dry air that generally brings good weather and light winds.
L = LOW PRESSURE: A low pressure system is a mass of warm, moist air that generally brings stormy weather with strong winds.
Let’s play! The
weather maps and isobars.
