A light breeze of less than five knots enhances the formation of radiation fog. This occurs because the slight breeze brings more moist air in contact with the cool ground, thus cooling the moist air layer more efficiently. A strong breeze squelches this process by mixing the moist surface air with the drier air above.
You may have noticed that fog tends to dissipate or "burn off" after the sun has been up for a short while. This occurs because some sunlight penetrates the fog and begins to warm the ground thus disrupting the fog creating cycle.
Advection fogs form as the result of wind moving moist air from above a warmer surface to a region above a cooler surface. The moist air cools to its dew point after coming in contact with the cooler surface producing fog. Advection fogs are typical in most coastal regions. During summer months, moist air is carried by the wind from warmer waters near the surface offshore.
When this warm air reaches cooler surface waters near the coasts the air cools and condenses creating a fog. Advection fogs often provide an important moisture source for surrounding biological systems in coastal regions. Upslope fogs form when moist air flows upslope in mountainous regions.
With this upward movement the air cools to it's dew point causing condensation and fog formation. Upslope fog is common on the eastern side of the Rocky Mountains. Upslope fogs can persist for many days in some regions.
Evaporation or mixing fog is the mixing of two unsaturated air masses to produce a fog. If moist air meets and mixes with cooler air resulting in saturation, a fog forms. Mixing fogs are common in ski areas during times of rainfall. As rain falls onto the snow it begins to melt. The melting process extracts heat from the surrounding environment, including the air close to the ground.
For readily forms in the cool, rain-saturated air. When you breathe condenses in front of your face on a cold morning you are staring at another example of a mixing fog. In the U. Three major regions stand out as having the most days with heavy fog:. Ships travelling the ocean off of Europe produce aerosols as they burn fuel, and those aerosols help to form low clouds in the shallow, cool, and moist layer of marine air that exists there.
The nuclei that help to form cloud clouds are extremely small, 0. Most condensation nuclei come from the soil, the ocean sea salt , and the burning of vegetation and fossil fuels. These aerosols then eventually get washed out by precipitation, which cleanses the air of them. Since clouds act as a natural sunshade, more or less cloud cover can cause global cooling or global warming. The mechanism Svensmark describes involves how much solar activity changes the amount of cosmic rays entering the atmosphere, which have been demonstrated in the laboratory to be able to form cloud condensation nuclei.
A cloud is a mixture of gas, liquid and solids. The water rises, cools, and condenses. A cloud is formed! Clouds form when warm wet air rises and condenses in cold air. The second reason that clouds can float in the air is that there is a constant flow of warm air rising to meet the cloud: the warm air pushes up on the cloud and keeps it afloat.
Less light is reflected. The rain cloud appears black or gray. When the water vapor meets the cold air found high in the sky, the gas condenses to liquid and forms cumulus clouds. While these fluffy-white clouds look like soft pillows of cotton, they are actually composed of small water droplets. Clouds do freeze in extreme temperatures.
Cirrus clouds, which are the highest, are not liquid droplets, but rather ice crystals. The list of cloud types groups the main genera as high cirrus, cirro- , middle alto- , multi-level nimbostratus, cumulus, cumulonimbus , and low stratus, strato- according to the altitude level or levels at which each cloud is normally found. Answer Brontide Other types of clouds include cirrocumulus, altostratus, and nimbostratus, named by the level of altitude at which they usually appear.
The foundation consists of 10 major cloud types. In addition to cirrus, stratus, cumulus, and nimbus clouds, there are cirrostratus, cirrocumulus, altostratus, altocumulus, stratocumulus, nimbostratus, and cumulonimbus clouds.
