ÚLTIMA HORA: CHEGA UNHA PROFUNDA BORRASCA

Podes ler a cobertura que fai da nova a Voz de Galicia

«Xynthia» cruzará Galicia de sur a norte

Son especialmente interesantes os mapas e a animación que aparecen neste enlace.



Aquí aparecen outras fotos e mapas interesantes:

Combinando a imaxe de satélite coa de isobaras:



E o de isobaras da Metoffice:



Fíxate que é unha borrasca pequena pero moi fonda, similar ao que acontece cos ciclóns tropicais. Pode chegar a baixar aos 968 mb de presión no seu centro, eso explica que as isobaras estén tan xuntas e polo tanto que provoquen fortes ventos, como ves de dirección sur. É unha masa de aire tropical moi cálida e húmida que provocará fortes chuvias e subida das temperaturas. Meteogalicia indica que hai alerta vermella, co cal o máis aconsellable é quedar na casa.

INTRODUCTION. HORRIBLE GEOGRAPHY

In this and other entries we can find exercises and texts taken from the excellent serie of books "Horrible Geography", published by Scholastic Children's books and writen and drawn by Anita Ganeri and Mike Philips.

. STORMY WEATHER

Are you brave enough to make a forecast? Look at this drawing and try to do it. Find a weather map for tomorrow here





Meteorologists use weather maps to plot the weather and to work out what it's going to happen. Make your forecast and check it, wait a few days and see. And remember that even the experts sometimes get things wrong.


. What on earth is a hurricane?

They're hair-raising hurricanes in the Atlantic, thundering typhoons in the Pacific, savage cyclones in the Indian Ocean, and in Australia they're known as willy-willies. But call them what you like, they all mean exactly the same thing. Furiously spinning superstorms which rage across tropical seas. HURRICANES ARE THE MOST DANGEROUS STORMS ON EARTH! They claim more lives and cause more damage than all other stormy weather put together.

A hurricane begins over the sea. But it's a bit choosy about which sea it picks. It must be nice and warm and humid. Somewhere truly tropical, like the Caribbean Sea. The mixture of warmth and water vapour's vital - it's the violent hurricane's ideal lunch, and it's what makes clouds and rain. By the way, a hurricane sucks up about two BILLION tonnes of moisture a day, then chucks it all back down as rain!

Inside a hurricane

1 Warm sea heats air above it. Warm, moist air rises quickly...

2 ...creating low pressure at the surface. More air sweeps in, then starts spiralling upwards.

3 The Earth's rotation makes the rising air twist round a centre called the eye.

4 Rising air cools, condenses and makes towering thunderclouds and torrential rain.

5 The hurricane spins away. Byeee!

Hurricane winds blow anticlockwise north of the equator and clockwise to the south.

INTRODUCTION. THE WEATHER

As a starter activity we could start the geography class everyday or once a week with the weather forecast for Europe.

We can watch it at BBC



Before or after watching it, we can work with the key words:

STORMS/STORMY
SHOWERS/PLENTY SHOWERS
DEGREES
DRY
TEMPERATURES
WARM
HUMIDITY
SUNSHINE
HIGH/LOW PRESSURE

We could also analyse the pressure map (in this case Wednesday/July/8/2009)
