What features influence where a jet stream goes?
The seasons of the year, location of low and high pressure systems and air temperature all affect when and where a jet stream travels. The greater the difference in air temperature, the faster the jet stream, which can reach speeds of up to 250 mph (402 kph) or greater, but average about 110 mph (177 kph).
Which is one function of a weather balloon?
A weather balloon, also known as sounding balloon, is a balloon (specifically a type of high-altitude balloon) that carries instruments aloft to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde.
How long does a weather balloon stay in the air?
around 2 hours
Can a weather balloon lift a person?
If you weigh 50 kilograms (about 110 pounds), then you weigh 50,000 grams. Divide your 50,000 grams by the 14 grams per balloon and you find that you need 3,571.42 balloons to lift your weight. You might want to add 500 more if you actually would like to rise at a reasonable rate.
How far does a weather balloon travel?
Weather balloons can rise to an altitude of 24 miles (39 kilometers) or more before they burst, and a payload may land (via parachute) up to 75 miles (120 km) away, depending on wind conditions at the launch site, Maydell said.
How high can a normal balloon go?
In reality, there are two major constraints: the strength of the balloon material, and Archimedes’s principle. As a balloon ascends, the pressure of the surrounding air drops while the helium inside expands. Toy balloons burst at around 10km, while professional meteorological balloons reach heights of 30km.
What happens when you let a balloon go in the sky?
One is that atmospheric pressure is dramatically reduced at high altitudes, so a helium balloon expands as it rises and eventually explodes. But the elasticity of rubber decreases at very low temperatures so it is possible that helium balloons shatter into much smaller pieces as is often claimed.
Can you make a balloon Garland the day before?
A balloon garland lasts at least a week, so no need to stress yourself creating it day-of your party; it can totally be prepped days in advance . Helium balloon arches will only last a day, maybe two.
How far in advance can I make a balloon arch?
You can blow them up 1-2 days before and keep the garland indoors (the heat causes them to shrink) until your party. A lot of the balloons will stay inflated much longer but they will look the best this way!
