Study Guide for Weather Formative - Storms & Predicting Weather
| Question | Answer |
|---|---|
| How does a Thunderstorm form? | warm air is quickly pushed up by a cold front |
| How does lightning form? | positive/negative charges build up in a storm cloud; spark caused as these charges to jump from one place to another in the cloud, from cloud to cloud, or from the cloud to the ground |
| What conditions must occur for a thunderstorm to form? | a fast moving cold front runs into an area of hot, humid air |
| How does a snowstorm/blizzard form? | if air stays colder than 0 degrees C (32 degrees F) and precipitation falls as snow |
| What conditions must occur for a snowstorm/blizzard to form? | air must be colder than 0 degrees C (32 degrees F) |
| How does a tornado form? | cold, dry air mass quickly pushes up a warm, humid air mass; the different winds created begin to push the air in a circular pattern |
| What conditions must occur for a tornado to form? | cold, dry air quickly pushes warm, humid air up; forms over land areas |
| How does a hurricane form? | as warm ocean waters quickly evaporate; air rises and forms clouds as more evaporation happens; wind speed/rainfall increases |
| What conditions must occur for a hurricane to form? | warm ocean waters; low pressure system; this allows a lot of evaporation |
| Where do hurricanes form? | warm ocean waters |
| Where do tornadoes form? | over land |
| When do hurricanes form? | Summer to Fall; the “Season” is June – November because the ocean has had all summer to heat up |
| When do tornadoes form? | spring & early summer as ground is heating up from longer days |
| What type of damage does a hurricane do? | storm surge and high winds |
| What type of damage does a tornado do? | severe damage to all property from high winds |
| What are the results of storm surges during a hurricane? | high waves, severe flooding, building damage, and beach erosion |
| What are the results of a high winds during a hurricane? | downed trees, power lines, damage buildings, etc. |
| What do you do to stay safe during a hurricane? | Evacuate |
| What do you do to stay safe during a tornado? | Seek shelter in a storm shelter, the basement, or the lowest floor of building in a room without windows |
| What information do meteorologists need to predict the weather? | Temperature, air pressure, relative humidity, wind speed and direction & location of the jet streams |
| What is an isobar? | curvy lines on a map that connect areas with the same air pressure |
| What is isotherm? | curvy lines on a map that connect places with the same temperature |
