Weather and climate paula

  1. 1. BY PAULA
  2. 2. WEATHER AND CLIMATE WEATHER Refers to atmospheric conditions at a specific moment. CLIMATE Refers to the typical atmospheric conditions in an area.
  3. 3. ATMOSPHERIC CONDITIONS  Temperature is the amount of heat in the atmosphere. Thermometer.  Precipitation is water that falls from the sky. Pluviometer.  Wind is the movement of air in the atmosphere. The wheater vane and anemometer.  Atmospheric pressure is caused by the weight of the air in the atmosphere. Barometer.
  4. 4. FACTORS THAT INFLUENCE CLIMATE • LATITUDE: Climate zones that are near the Equator are usually warm. • DISTANCE FROM BODIES OF WATER: Temperatures are less extreme near seas or oceans. In coastal areas, summers are cooler and winters are milder. • ALTITUDE: Place at higher altitudes are colder than places at lower altitudes. The climate is often wetter.
  5. 5. THE EARTH´S CLIMATE ZONES The Earth has got many climate zones, but we can classify them into three general categories: 1. Hot (or torrid) climate. 2. Temperate climate. 3. Cold (or frigid) climate.
  6. 6. HOT CLIMATES • Equatorial climates have high temperatures and lots of precipitation. • Tropical climates have high temperatures. They receive lots of precipitation in summer, but the weather is dry in winter. • Desert climates receive very little precipitations. They can also have very extreme temperature.
  7. 7.  Oceanic climates have mild temperatures. They receive a lot of precipitation, especially in winter. (Galicia)  Mediterranean climates have mild winters and hot summers. It rains in the spring and autumn, but summers are dry. (Murcia)  Continental climates have cold winters and hot summers. They don’t receive very much precipitation. (Madrid)
  8. 8. COLD CLIMATES • Mountains climates are cold. There is more precipitation at high altitudes. • Polar climates have a very low temperature.
  9. 9. CLIMATE ZONES IN SPAIN Spain has got a variety of climate zones. • Latitudes. Spain is in the North Temperate Zone, but the Canary Island are closed to the Tropics • Spain has got coastal regions where temperature are more extreme. • Spain has got high, mountainous regions where temperature are lower.

  11. 11. Climate change It is caused by an increase in the Earth´s temperature. The main cause of this change is an increase in waste gases, like carbon dioxide, in the Earth´s atmosphere. Most of the waste gases come from petroleum products that are used in factories, cars and people´s homes. These gases accumulate in the atmosphere and stop heat from escaping into space. This increases the Earth´s temperature. It is called the greenhouse effect and it causes global warming
  12. 12. The main consequences of climate change • HIGHER SEA LEVELS: The ice in polar zones is melting. This is going to caused floods in coastal regions. • MORE SEVERE WEATHER: Higher temperature are going to cause more violent storms. • DROUGHT: Some regions are going to receive less precipitation, so they won´t have enough water. • EXTINCTION: If the temperatures keep increasing, many plant and animal species are going to disappear.
  13. 13. CLIMATE AND NATURALS DISASTERS • Strong winds can cause serious damage to building and trees. • Torrential rains can cause dangerous floods. • Droughts are long periods of time with little or no rain. • High temperature can cause forest fires.
  14. 14. STRONG WINDS HURRICANE • It is a large tropical storm. It can produce winds of more than 250 kilometres per hour. TORNADO • It is a column of air that comes from a storm cloud and rotates violenty. They can be very destructive.
