What are types of front?
There are four basic types of fronts, and the weather associated with them varies.
- Cold Front. A cold front is the leading edge of a colder air mass. …
- Warm Front. Warm fronts tend to move slower than cold fronts and are the leading edge of warm air moving northward. …
- Stationary Front. …
- Occluded Front.

What causes the four types of fronts?
The type of front depends on both the direction in which the air mass is moving and the characteristics of the air mass. There are four types of fronts that will be described below: cold front, warm front, stationary front, and occluded front.
What are the 4 types of air masses?
When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm. Meteorologists identify air masses according to where they form over the Earth. There are four categories for air masses: arctic, tropical, polar and equatorial.
What are the four types of fronts and what type of weather does each type bring?
There are four types of weather fronts, cold, warm, stationary, and occluded. Cold fronts are associated with cumulus cloud formation and thunderstorms. Warm fronts are associated with gray skies and drizzle. Occluded fronts result in both warm front and cold front type weather on either side of the front.
What are the 4 types of weather?
Weather is the combination of four factors––temperature, wind, precipitation, and sunlight and clouds––that occur at a given place and time.
What are cold and warm fronts?
A cold front extends to the south of the low pressure center, with a warm front to the east. Warm air is located ahead of the cold front and behind the warm front (the so-called "warm sector"), while cool air exists ahead of the warm front and cold air is present behind the cold front.
How many fronts are there?
four different There are four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts.
What are cold fronts and warm fronts?
A cold front extends to the south of the low pressure center, with a warm front to the east. Warm air is located ahead of the cold front and behind the warm front (the so-called "warm sector"), while cool air exists ahead of the warm front and cold air is present behind the cold front.
What are the 4 basic types of air masses describe the characteristics of each?
Air masses are commonly classified according to four basic source regions with respect to latitude. These are Polar (cold), Arctic (very cold), Equatorial (warm and very moist), and Tropical (warm).
What is cold front and warm front?
A cold front extends to the south of the low pressure center, with a warm front to the east. Warm air is located ahead of the cold front and behind the warm front (the so-called "warm sector"), while cool air exists ahead of the warm front and cold air is present behind the cold front.
What are the 5 main types of weather?
The five main types of weather are: sunny, cloudy, windy, rainy, and stormy.
What are the five main types of weather?
The five types of weather are sunny, rainy, windy, stormy, and cloudy. Many of these types of weather can occur at the same time.
Is low pressure hot or cold?
Cold air is more dense, therefore it has a higher pressure. Warm air is less dense and has a lower pressure associated with it.
What is warm front and cold front?
Basically, a weather front represents a boundary between two different air masses, such as warm and cold air. If cold air is advancing into warm air, a cold front is present. On the other hand, if a cold air mass is retreating and warm air is advancing, a warm front exists.
What is an occluded front in weather?
An Occluded Front forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward.
What are the 4 types of air masses and how do they affect the weather in North America?
Maritime air masses form over oceans and are humid. Continental air masses form over land, in the middle of continents, and are dry. Four major types of air masses influence the weather in North America: maritime tropical, continental tropical, maritime polar, and continental polar.
What are the 4 weather types?
A selection of possible weather conditions with visible evidence of the four factors—temperature, precipitation, wind, and sunlight and clouds—is included in the “Types of Weather” gallery.
What are the 4 Weathers?
The four seasons—spring, summer, fall, and winter—follow one another regularly. Each has its own light, temperature, and weather patterns that repeat yearly. In the Northern Hemisphere, winter generally begins on December 21 or 22. This is the winter solstice, the day of the year with the shortest period of daylight.
What causes wind?
During the day, air above the land heats up faster than air over water. Warm air over land expands and rises, and heavier, cooler air rushes in to take its place, creating wind. At night, the winds are reversed because air cools more rapidly over land than it does over water.
Is rain high or low pressure?
Low pressure Low pressure is what causes active weather. The air is lighter than the surrounding air masses so it rises, causing an unstable environment. Rising air makes the water vapor in the air condense and form clouds and rain for example. Low pressure systems lead to active weather like wind and rain, and also severe weather.
What is occluded front in geography?
An Occluded Front forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward.
What is cold front weather?
A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. Cold fronts generally move from northwest to southeast. The air behind a cold front is noticeably colder and drier than the air ahead of it.
What does a purple weather front mean?
Occluded fronts Occluded fronts point to a decrease in intensity of the parent weather system and are indicated by a purple line with alternating triangles and half-moons on the side of its motion.
What are the 5 main air masses?
The air masses in and around North America include the continental arctic (cA), maritime polar (mP), maritime tropical (mT), continental tropical (cT), and continental polar (cP) air masses.
Why are there 4 seasons?
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
What happens in the 4 seasons?
In spring, the weather begins to get warmer and trees and other plants grow new leaves. Summer is the hottest season and has long, usually sunny, days. In autumn, the weather becomes mild and leaves start falling from many types of trees. Winter is the coldest season, with short days.
What is wind class 7?
In simple terms, the wind is nothing but moving air. The air movement is always from high pressure to low-pressure areas.
Why is wind cold?
After they've made contact, the air molecules must move away, carrying what used to be our body heat with them in the form of jiggling. The faster the turnover of air molecules bumping against and then moving off our skin, the cooler we become. That's why, on a 90-degree day, you can find me in front of a fan.

What is cold front in geography?
A cold front develops when cold air meets an area of warm air. The warm air has a low density so it rises up above the cold air. Large storm clouds develop here as the temperature lowers and the water in the clouds starts to condense and forms rain. Cold Front.
