Precipitation
Pellets of frozen rain that fall in showers from clouds
What is hail
What is wind speed vs wind gust
Speed = long period of time, the average over a period of time
Gust = short, sudden burst of wind that is typically higher than the average speed.
What material is a weather balloon typically made of?
latex
True/False: Tornados are a form of short term weather conditions
False.
Why is a hail cloud dense?
It's particles are cold, which makes the items have to move quicker since there's less warm air to move.
Hail is considered a _____ term form of precipitation while a drought is considered a ______ term form of precipitation.
Short, Long
What does it mean to look at weather conditions? What are typical things that you would be looking for?
Temperature, wind, clouds, and chance of precipitation
What 3 things do weather balloons measure?
Humidity, temperature, and geographical location
True/False: A weather balloon goes higher than an airplane
True.
Weather balloons often times get caught up in what?
Trees, or end up failing in the ocean, or get taken down by airplanes.
Describe why hail clouds are dark
They are full of water that is being frozen in the atmosphere
Why does humidity typically drop when it's hailing?
Because the particles from the clouds are typically cold and bring cold air down from the stratosphere.
What is the device on a weather balloon called?
Radiosonde
True/False: Weather conditions for hail typically measures the altitude of a hail cloud.

What is the second layer of the atmosphere called?

True/False. Why happens after a hail storm? What do weather conditions typically look like after.
Theres fog on roof/surfaces, the sun will typically come out and humidity will rise again.
Describe how hail works forms and falls. What does a typical day look like before - and what goes on during a hail storm?
Hail will form in clouds from a colder area of the atmosphere. Before hail falls, it's typically on a humid day and windy day. During the storm, there will be wind gusts and humidity levels drop.
What 5 conditions of weather does hail data typically look at?
Time, temp, humidity, wind speed, wind gust.
Where does a weather balloon typically measure it's conditions and why?
Stratosphere, because it can help predict what's going to be on the ground.
True/False: Weather balloons measure, time, humidity and temperature.
false.
