Fronts
What is a front?
A weather front is a boundary separating bands of thunderstorms and severe weather, and may on occasion be preceded by squall lines or dry lines.
What are jet streams.
Fast flowing air currents
What does a weather map do?
A weather map and its symbols gather a lot of weather information quickly and without using a lot of words. Just as equations are the language of mathematics, weather symbols are the language of weather.
What are air masses
An air mass consists of a vast quantity of air that possesses a common temperature and moisture content throughout its reach.
When does a weather pattern occur?
A weather pattern occurs when the weather stays the same for days or weeks at a time.
Where does a warm front form?
Warm fronts often form on the east side of low-pressure systems where warmer air from the south is pushed north.
Where do they form ( north ,south,etc)
East
What does a isotherm show
Maps using isotherms show temperature gradients
What are the different types of air masses
Continental polar marine, time polar, continental tropical marine, time tropical
what are the common weather patterns?
Hot and dry, cold, rainy and unusual long-lasting weather patterns
How do they form
Jet streams form when warm air masses meet cold air masses in the atmosphere
What does a isotach show
They analyze lines of equal wind speed
What do fronts and air masses have in common
When two different air masses collide, the warmer air rises above the colder, denser air. In the northern hemisphere, most fronts travel from west to east carrying clouds and rain. As a front passes through an area, changes in wind speed and direction, atmospheric pressure and moisture result.
What is the weather pattern in winter
During winter, the weather pattern is cold
How long does the effect of a cold front last?
The effects from a cold front can last from hours to days.
Why do aircraft use them
To boost their speed
Why do we need to understand the symbols on a weather map?
A weather map and its symbols are meant to convey a lot of weather information quickly and without using a lot of words. Just as equations are the language of mathematics, weather symbols are the language of weather, so that anyone looking at a map should be able to decipher the same exact information from it.
What are the four types of air masses and where does each form?
Polar forms over cold areas, tropical forms over warm areas, continental forms over land, and maritime forms over the oceans.
What is the weather pattern for summer
It is hot and dry
How does an occluded front affect weather
How do they affect weather
The fast-moving air currents in a jet stream can transport weather systems across the United States, affecting temperature and precipitation.
What happens if there was no weather map
We would not be able to understand weather
How do they affect weather patterns
By creating fronts and jetstreams.
What causes weather patterns to change
Daily changes in the weather are due to winds and storms. Seasonal changes are due to the Earth revolving around the sun.
