Model Answer
- Katabatic winds are also known as downslope winds. They tend to occur over cooled slopes. Katabatic winds happen when the air over a valley is cooler than the air in contact with sloping land. In most of the world, katabatic winds are a nocturnal phenomenon (i.e., typically occur at night) because they are caused by surface cooling, particularly when there is little cloud cover and the sun isn’t heating the air.
- Chinook is a local wind that blows on the eastern slopes of the Rocky Mountains in Canada, and is also known as a Foehn wind in other parts of the world. It's a warm, dry wind that can have a significant impact on the local area, especially during the winter season. Chinook winds can cause the temperature in an area to rise by 4–22 degrees Celsius, melting snow and affecting local pastures. Because of its ability to melt snow, Chinook winds are also known as "snow eaters".
- The Simoom is a strong, dry, and hot wind that blows in the deserts of the Arabian Peninsula, Israel, Jordan, Iraq, Palestine, and the Sahara. The word "Simoom" is Arabic for "poison wind" and refers to the wind's tendency to cause heatstroke.
- The Sirocco is a hot, dry, dusty wind that blows from the Sahara Desert towards the Mediterranean Sea and North Africa. It's a harmful wind that can reach hurricane speeds and has a significant impact on the weather and climate in the regions it affects.
