Wind talk
Sea breeze – during the day warm air rises over land and draws cooler air from the sea.
Land breeze – at night the sea is warmer than the land. Rising air over the sea draws the air from the land.
Gust – a sudden increase in wind speed, lasting only a few seconds.
Wind stirs your emotions. A gentle breeze feels good, especially on a hot day. When the wind picks up and dust or sand blows into your face, it becomes annoying. A warm dry mountain wind gets on your nerves and makes you feel sick. When the wind grows even stronger – tree branches break, roof tiles blow away – it becomes frightening.
Wind is very useful. For thousands of years, mankind used the wind to sail the oceans. Windmills ground the wheat or created electric power. Aircraft like the wind on their noses for short take-offs or landings. Wind disseminates plant seeds and pollen.
Wind is cruel, too. It causes considerable damage, injury and death: ships sink, aircraft crash, buildings collapse. A tornado needs only a few minutes to flatten your home, a cyclone threatens many kilometres of coastline, while winter storms bring traffic to a halt.
