🗑
|
||||
| Are these clouds low? | Yes
🗑
|
||||
| What color are stratus clouds? | Greyish
🗑
|
||||
| What does stratus clouds resemble? | Fog
🗑
|
||||
| What cloud causes light to no precipitation and cover the whole sky | Stratus Clouds
🗑
|
||||
| What is fog? | When air is cooled to its dew point near the ground
🗑
|
||||
| What cloud is fog? | Stratus
🗑
|
||||
| What are air masses? | HUGE bodies of air that forms over water or/and in tropical or polar regions
🗑
|
||||
| What determines the weather conditions of an air mass? | Temperature and humidity of the air masses as they form. Warm, cold, dry, or moist determines the weather as air masses move.
🗑
|
||||
| Describe fronts | Fronts are boundaries where air masses move and collide with each other. They are basically warm air and cold air meeting together.
🗑
|
||||
| How many types of fronts are there and what are the fronts names? | There are four fronts.
1. Warm Front
2. Cold Front
3. Stationary Front
4. Occluded Front
🗑
|
||||
| Describe a warm front | A warm air mass collides and rides over a cold air mass.
🗑
|
||||
| What type of weather does warm fronts bring? | Warm fronts may produce long periods of precipitation and warmer temperatures.
🗑
|
||||
| What does the symbol for a warm front look like? | Red semicircles in a line
🗑
|
||||
| Describe a cold front | A cold air mass collides and slides under a warm air mass
🗑
|
||||
| What type of weather does a cold front bring? | May produce thunderstorms and sometimes tornadoes and cooler temperatures.
🗑
|
||||
| Describe a stationary front | If neither a cold air mass or a warm air mass moves when they meet, it becomes a stationary front.
🗑
|
||||
| What type of weather does a stationary front bring? | Long periods of precipitation
🗑
|
||||
| Describe an occluded front | First you have a warm air mass that pushes into a cold air mass. Then, before it can move away, a cold air mass comes along after the warm air mass and sort of sandwiches the warm air mass.
🗑
|
||||
| What type of weather does occluded front bring? | Long periods of precipitation.
🗑
|
||||
| What forms high and low pressure systems? | Warm air rising on cold air sinking combined with the spinning of the Earth causes the air to spin
🗑
|
||||
| What type of weather does high pressure systems usually signal? | Fair weather
🗑
|
||||
| What direction do winds in a high pressure system circulate? | Clockwise direction
🗑
|
||||
| What type of weather comes with low pressure systems? | Rainy/stormy weather conditions.
🗑
|
||||
| What causes storms? | Storms occur when air pressure differences cause rapid air movement
🗑
|
||||
| What is a thunderstorm? | A storm with thunder, lightning, heavy rains, and strong winds.
🗑
|
||||
| What type of cloud are thunderstorms usually created in? | Large cumulonimbus clouds
🗑
|
||||
| How are thunderstorms formed? | They usually follow a cold front but can form within an air mass.
🗑
|
||||
| What is a tornado? | Rapidly whirling funnel shaped cloud that extends down from a storm cloud.
🗑
|
||||
| Describe a tornado | A tornado has very low pressure and strong winds. They can cause great damage to people and property.
🗑
|
||||
| How are tornado's formed? | Likely to form within the frontal regions with strong thunderstorms.
🗑
|
||||
| Describe a hurricane | *Low pressure tropical storm
*ONLY forms over warm ocean water
*Winds spin in a circular pattern around a center (eye)
*The lower the air pressure at the center, the faster the winds blow toward the center of the storm
🗑
|
||||
| What measurement unit is air pressure measurement | Milliliters
🗑
|
||||
| What measurement tool is air pressure measured in? | Barometer
🗑
|
||||
| wHAT IS THE SIMPLEST KIND OF BAROMETER? | Mercury Barometer
