Fronts come in four flavors: cold, warm, stationary, and occluded. Cold fronts occur when cold air is moving to displace warmer air; warm fronts are where warm air is replacing cold air.
A stationary front
, as its name suggests, has no movement and may linger for several days.

What is the most destructive storm on Earth?
Besides having unsurpassed intensity,
Super Typhoon Tip
is also remembered for its massive size. Tip's diameter of circulation spanned approximately 1,380 miles (2,220 km), setting a record for the largest storm on Earth. The storm's huge diameter was exactly the same as the distance from New York City to Dallas.
Where is the term hurricane used?
In
the North Atlantic, central North Pacific, and eastern North Pacific
, the term hurricane is used. The same type of disturbance in the Northwest Pacific is called a typhoon.
What is a large body of circulating air that has high pressure at its center and low pressure outside?
A high-pressure system
is a large body of circulating air with high pressure at its center and lower pressure outside of the system. Air moves from high pressure to low pressure.
Which front is most likely to last for days?
A stationary front
forms when a cold front or warm front stops moving. This happens when two masses of air are pushing against each other, but neither is powerful enough to move the other. Winds blowing parallel to the front instead of perpendicular can help it stay in place. A stationary front may stay put for days.
Where the most weather changes occur?
Weather is different in different parts of the world and changes over minutes, hours, days and weeks. Most weather happens in
the troposphere
, the part of Earth's atmosphere that is closest to the ground.
What is the strongest storm in history?
At 20:40 UTC on November 7,
Haiyan
made landfall in Guiuan, Eastern Samar at peak intensity. The JTWC's unofficial estimate of one-minute sustained winds of 305 km/h (190 mph) would, by that measure, make Haiyan the most powerful storm ever recorded to strike land.
What is the longest storm in history?
Hurricane John, also known as Typhoon John
, was both the longest-lasting and the farthest-traveling tropical cyclone ever observed.
What was the biggest storm ever?
Typhoon Tip
was the largest tropical cyclone on record, with a diameter of 1,380 mi (2,220 km)—almost double the previous record of 700 mi (1,130 km) set by Typhoon Marge in August 1951.
What is the calmest part of a hurricane?
Note
the eye
at the center. Skies are often clear above the eye and winds are relatively light. It is actually the calmest section of any hurricane. The eye is so calm because the now strong surface winds that converge towards the center never reach it.
What are 3 types of hurricanes?
- Category 1: Winds of 74-95 mph (119-153 km/h)
- Category 2: Winds of 96-110 mph (154-177 km/h)
- Category 3: Winds of 111-129 mph (178-208 km/h)
- Category 4: Winds of 130-156 mph (209-251 km/h)
- Category 5: Winds exceeding 157 mph (252 km/h)
When a hurricane hits land what is it called?
Landfall
is the event of a storm moving over land after being over water.
Which conditions are usually the effect of a low air pressure system?
A low pressure system has lower pressure at its center than the areas around it.
Winds blow towards the low pressure, and the air rises in the atmosphere where they meet
. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.
What causes high and low pressure?
Areas of high and low pressure are caused by
ascending and descending air
. As air warms it ascends, leading to low pressure at the surface. As air cools it descends, leading to high pressure at the surface.
What is the area where air masses meet and do not mix?
The area where the air masses meet and do not mix becomes
a front
. When air masses meet at a front, the colli- sion often causes storms and changeable weather.
