  • Tell us about a time you experienced heavy rain in your area. What did you observe about the clouds before, during, and after the rainfall?
  • What type of cloud is most commonly associated with thunderstorms and heavy rainfall?
    Cumulonimbus
  • At ground level, how are rain and hail similar?
    They can occur when the air is hot and moist.
  • What happens to air temperature when precipitation occurs?
    It can either increase or decrease depending on the type of precipitation
  • Imagine you are a weather forecaster in Hanoi. What types of precipitation would you expect to report about during the summer months? Explain why these types occur.
  • It is a cold winter day in New York City. The air temperature is below freezing in and below the clouds. What is the most likely form of precipitation?
    snow
  • Which cloud type is highest in the atmosphere and appears thin and wispy?
    Cirrus
  • It is a hot, summer day, and a thunderstorm is possible. Which types of precipitation are most likely to occur?
    Rain and hail
  • In Vietnam during the monsoon season, what is the most common form of precipitation?
    Heavy rainfall
  • Which cloud type often appears as "cotton balls" in the sky?
    Cumulus
  • It is winter, and you want to know where it might snow today. Look at the predicted temperature for each state. Then identify the states where it could snow today.
    North Dakota, Michigan
  • Which condition is necessary for snow to form?
    Temperatures below 32°F (0°C) throughout the cloud and to the ground
  • What type of precipitation is most common during spring in four-season countries?
    Rain showers and occasional thunderstorms
  • Hail forms when:
    Water droplets are carried up and down in a cloud, forming layers of ice
  • Sleet occurs when:
    Snow partially melts and refreezes as it falls
  • Why do the northern United States get more snow than the southern states?
    Because there are colder temperatures in the winter months in the northern states
  • In four-season countries, when does freezing rain most commonly occur?
    Late fall to early spring
  • What type of clouds are flat and gray, often bringing light, steady precipitation?
    Stratus
  • which ones do you think are most likely to produce rain? Explain your reasoning.
  • During winter, precipitation is most likely to fall as snow when:
    Cloud and ground temperatures are below freezing
  • During Vietnam's dry season, which type of precipitation is most common?
    Light scattered showers
  • Which cloud type is most likely to produce drizzle?
    Stratus
  • There are some clouds forming in the sky on a hot day, but inside the clouds, there are freezing temperatures. Which form of precipitation would you expect?
    Hail
  • Which season typically brings the most rainfall to Northern Vietnam?
    Summer
  • Which form of precipitation occurs when water droplets fall from clouds at temperatures above freezing?
    Rain
