What type of clouds are associated with a warm front?
Warm fronts produce clouds when warm air replaces cold air by sliding above it. Many different cloud types can be created in this way: altocumulus, altostratus, cirrocumulus, cirrostratus, cirrus, cumulonimbus (and associated mammatus clouds), nimbostratus, stratus, and stratocumulus.
What do nimbostratus clouds indicate?
Nimbostratus is generally a sign of an approaching warm or occluded front producing steady moderate precipitation, as opposed to the shorter period of typically heavier precipitation released by a cold-frontal cumulonimbus cloud. Precipitation may last for several days, depending on the speed of the frontal system.
What is the temperature in a nimbostratus cloud?
The tops of dark, steadily precipitating nimbostratus clouds can be as shallow as 2–3 km and even be above freezing in temperature, or they may reach above 13 km (at cirriform cloud levels) and be as cold as −80°C.
What type of cloud produces rain in a warm front?
Stratus clouds
Stratus clouds often form at the boundary of a warm front, where warm, moist air is forced up over cold air.
What weather is associated with this cloud type?
Cumulonimbus clouds are thunderstorm clouds. High winds can flatten the top of the cloud into an anvil-like shape. Cumulonimbus clouds are associated with heavy rain, snow, hail, lightning and even tornadoes….
| Cloud Group | Cloud Height | Cloud Types |
|---|---|---|
| High Clouds = Cirrus | Above 18,000 feet | Cirrus Cirrostratus Cirrocumulus |
What weather is associated with cumulus clouds?
Mostly, cumulus indicates fair weather, often popping up on bright sunny days. Though if conditions allow, cumulus can grow into towering cumulus congestus or cumulonimbus clouds, which can produce showers.
What causes nimbostratus?
Nimbostratus clouds are formed when warm, moist air is gradually lifted over a large area, typically produced by a warm front. With warm fronts, the cloud layer is much more stable, resulting in the formation of nimbostratus clouds.
What weather does a cumulus cloud bring?
What is the altitude of nimbostratus?
The main body of Nimbostratus almost invariably occurs at altitudes between 2 km and 4 km (6 500 ft and 13 000 ft) in polar regions, between 2 km and 7 km (6 500 ft and 23 000 ft) in temperate regions and between 2 km and 8 km (6 500 ft and 25 000 ft) in tropical regions.
What’s the difference between stratus and nimbostratus?
Both nimbostratus and stratus clouds can be found at the same height, are both relatively featureless, and are both the same light gray to dark gray color. The biggest differentiator is that nimbostratus clouds contain rain, whereas stratus clouds only contain rain on the rarest of occasions.
Where does rain occur in a warm front?
Where does rain occur in a warm front? Rain occurs along and in front of a warm front.
Can cumulus clouds produce rain?
Normally, cumulus clouds produce little or no precipitation, but they can grow into the precipitation-bearing congests or cumulonimbus clouds. Cumulus clouds can be formed from water vapour, supercooled water droplets, or ice crystals, depending upon the ambient temperature.
How are nimbostratus clouds formed in the weather?
The way nimbostratus clouds form is an important part of understanding the weather they produce. Nimbostratus clouds are formed when warm, moist air is gradually lifted over a large area, typically produced by a warm front. Warm fronts move much more slowly than cold fronts, resulting in a more gradual, gentle lifting of the moist, warm air.
Where does nimbostratus occur on the synop report?
It is coded C M 2 on the SYNOP report. Nimbostratus occurs along a warm front or occluded front where the slowly rising warm air mass creates nimbostratus along with shallower stratus clouds producing less rain, these clouds being preceded by higher-level clouds such as cirrostratus and altostratus.
Which is the best description of an altostratus cloud?
Altostratus clouds are “strato” type clouds (see below) that possess a flat and uniform type texture in the mid levels. They frequently indicate the approach of a warm front and may thicken and lower into stratus, then nimbostratus resulting in rain or snow.
How are fractostratus clouds and scud clouds formed?
These are known as fractostratus clouds, or scud. The way nimbostratus clouds form is an important part of understanding the weather they produce. Nimbostratus clouds are formed when warm, moist air is gradually lifted over a large area, typically produced by a warm front.
