Cirrus Clouds-Fair Weather, Perhaps a Storm Approaching

Cirrus clouds generally occur in fair weather, but they can also hearld the leading edge of a far-away storm or may mark the edge of a storm passing to the north. Cirrus clouds are formed by the freezing of rising water vapor into tiny ice crystals. ...

What cloud indicates an oncoming storm?

Cumulonimbus are generally known as thunderstorm clouds. High winds will flatten the top of the cloud into an anvil-like shape. Cumulonimbus are associated with heavy rain, snow, hail, lightning, and tornadoes. The anvil usually points in the direction the storm is moving.

What weather do cirrus clouds indicate?

Cirrus clouds are the most common of the high clouds. They are composed of ice and are thin, wispy clouds blown in high winds into long streamers. Cirrus clouds are usually white and predict fair to pleasant weather. ... Cirrocumulus clouds are usually seen in the winter and indicate fair, but cold weather.

Why do cirrus clouds indicate a change in weather?

What weather is associated with cirrus clouds? They often form in advance of a warm front, where the air masses meet at high levels, indicating a change in the weather is on the way. Technically these clouds produce precipitation but it never reaches the ground. Instead, it re-evaporates, creating virga clouds.

What kind of clouds precede strong fronts and storms?

Cumulonimbus clouds (refer to photo above) often precede or accompany the cold front and bring showers and thunderstorms.

What is the 4 types of clouds?

The Four Core Types of Clouds

Cirro-form. The Latin word 'cirro' means curl of hair. ...
Cumulo-form. Generally detached clouds, they look like white fluffy cotton balls. ...
Strato-form. From the Latin word for 'layer' these clouds are usually broad and fairly wide spread appearing like a blanket. ...
Nimbo-form.

Do cirrus clouds bring rain?

They are wispy, being composed entirely of ice crystals falling through the atmosphere. If Cirrus are carried horizontally by winds moving at different speeds, they take a characteristic hooked shape. Only at very high altitudes or latitudes do Cirrus produce rain at ground level.

Why are cirrus clouds so thin?

Because humidity is low at such high altitudes, this genus-type tends to be very thin. Cirrus clouds are composed of ice crystals that originate from the freezing of super cooled water droplets in regions where air temperature is lower than -20 °C or -30 °C.

Are cirrus clouds dangerous?

Cirrus clouds are high altitude clouds made of ice crystals that are generally found above 20,000 feet above ground level (AGL). Since they form in stable air, they usually don't pose a risk as far as turbulence or icing.

Is a cirrus cloud high or low?

High-level clouds:

The three main types of high clouds are cirrus, cirrostratus, and cirrocumulus. Cirrus clouds are wispy, feathery, and composed entirely of ice crystals. They often are the first sign of an approaching warm front or upper-level jet streak.

Can clouds predict weather?

One of the easiest ways to predict weather is to look at the clouds. There are many different types of clouds in the troposphere. Different clouds mean different types of weather. One of the easiest ways to predict weather is to look at the clouds.

How high up are cirrus clouds?

Cirrus Clouds: thin and wispy. The most common form of high-level clouds are thin and often wispy cirrus clouds. Typically found at heights greater than 20,000 feet (6,000 meters), cirrus clouds are composed of ice crystals that originate from the freezing of supercooled water droplets.

At which point will a cloud form?

Explanation: Clouds will form at a point when rising air decreases in pressure and cools below the dew point. Before clouds are formed to consist of water and ice, water vapor (the gaseous form of water) rises up into the sky by the process of evaporation.
