[12:01.38]The last reading.
[12:03.51]US Climate
[12:06.23]The United States is one of the biggest countries in the world.
[12:10.81]It has all sorts of geography,
[12:13.23]from deserts to beaches, mountains to flatlands.
[12:17.49]These conditions help create all sorts of weather:
[12:21.25]mild, moderate and extreme.
[12:24.91]In the summer, some areas get very hot and the air is very wet.
[12:30.88]But others have dry air, so the heat does not feel so bad.
[12:36.05]In the winter, parts of the country get cold and snowy
[12:40.15]while others stay warm and sunny.
[12:43.45]This is the difference between, for example,
[12:46.14]the East Coast and the West Coast.
[12:49.43]The oceans affect weather along the coasts.
[12:52.36]The Pacific coast has smaller temperature changes
[12:56.21]and calmer conditions than along the Atlantic.
[13:00.62]Hurricanes are ocean storms that strike mainly in the Southeast.
[13:05.48]The hurricane season is, officially, June through November.
[13:10.29]Tornadoes are a risk across the country.
[13:14.24]These are locally severe windstorms in the spring and summer.
