[2015] Hanna S: Cliffhanger

Katabatic winds are special winds that flow from a high elevation to a low elevation. The particles in these winds are slow moving, more compact, and have less energy than the surroundung air. Coler air sinks while hot air, and since Katabtic winds have a higher density (they are colder), they just ride the slop down. After the slope, they continue onto the flatland.

Most Katabatic winds happen in very cold places, like Antaritica. There are two types of Katabatic winds: warm, dry Katabatic Winds or cold, usually dry Katabatic Winds. The warmer winds are called Foehn Winds, occuring on a mountain side in a mountain pass. Cold Katabtic winds are the most common.

Altitude sickness is very common at the height of 8,000 feet, or 2,400 meters. It is caused from the lack of air pressure. So, if you were on Mountain Everest, there is less air "stacked" on top of you. There is the same amount of air but it's more spread apart than down at the bottom.

When you have altitude sickness, your body goes through a variety of symptoms, depending on what level you are on. The three different altitudes are High Altitude, Very High Altitude, and Extreme Altitude. The higher the altitude, the worse the symptoms.

Not only do they happen in colder places, but the winds can form better at night. This allows the particles to become more dense than the surrounding air.

Symptoms of altitude sickness include dizziness, trouble sleeping/stay asleep (Insomnia), nausea, feeling unsteady, and loss of appetite. They differ in everyone. Symptoms are worse at night because of the cold, dizziness, trouble sleeping/stay asleep (Insomnia), nausea, feeling unsteady, and loss of appetite. They differ in everyone. Symptoms are worse at night because it gets more cold. The particles lose energy, becoming more compact and slow moving.

Katabatic winds are special but there is also different types of winds, too. Anabatic wind is one of those types. It almost has the same science to it, but this wind happens during the day. The sun heats the surface of the slope and the air over it, making it have a higher density than the atmosphere over the valley or plain, causing it to rise.

Think of air pressure like a swimming pool. Say you swam to the very deepest point, so around ten feet. There's a whole bunch of water molecules above and on top of you. This causes a lot of pressure on your body. At the shallow end, around three feet, there's practically no water particles on top of you, causing less pressure. The deep end acts like sea level, where plenty of air molecules are present, while the shallow end acts like the peak of a mountain, where there is less pressure and air.

Fun Facts:Some katabatic winds can travel down a slope at the speed of a hurricane, but many are more gentle, at a speed of eighteen miles per hours.Fatality may occur when you have altitude sickness.The symptoms of altitude sickness only last about one or two days, but doctors recommend that you drink plenty of water and take it easy once you go into higher altitudes.
