or, by Ida Eriksen, Niels Bohr Institute. The reason why thunderstorms can be so powerful, in addition to large day and nighttime temperature variations at the earth's surface, also relates to a self-reinforcing mechanism. Winds meet at the center of the low pressure system and have nowhere to go but up. In meteorology, a cloud is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body or similar space. Your opinions are important to us. Cirrostratus clouds are thin, white clouds that cover the whole sky like a veil.
They are lower than cirrus clouds, but still quite high.
We do not guarantee individual replies due to extremely high volume of correspondence. If the difference is great, we see more thunderstorms, and subsequently, more cloud bursts," explains Jan Olaf Härter, an associate professor at the University of Copenhagen's Niels Bohr Institute. Visit us on Instagram, clouds form as air warms up near the Earth's surface and rises, clouds, such as lenticular and stratus clouds, form when wind blows into the side of a mountain range, Clouds also form when air is forced upward at areas of low pressure, Weather fronts, where two large masses of air collide at the Earth’s surface, also form clouds. When the temperature difference is large, the risk of severe thunderstorms increases. Creative Cloud is a collection of 20+ desktop and mobile apps and services for photography, design, video, web, UX and more. Altocumulus clouds have several patchy white or gray layers, and seem to be made up of many small rows of fluffy ripples. Nimbostratus, stratocumulus, and stratus clouds can also form at cold front. When it evaporates—that is, rises from Earth’s surface into the atmosphere—water is in the form of a gas, water vapor. Click here to sign in with Your feedback will go directly to Science X editors.

In 2011, large parts of Copenhagen were submerged by deluges that lead to roughly 6 billion kroner in damages reported to insurance companies. They are beautiful in sunsets, and their varying sizes and shapes can make them fun to observe!Weather prediction: Fair, Stratus cloud often look like thin, white sheets covering the whole sky. The difference between day- and nighttime surface temperatures is dependent upon the moisture content of soil.
Weather fronts, where two large masses of air collide at the Earth’s surface, also form clouds by causing air to rise. The information you enter will appear in your e-mail message and is not retained by Phys.org in any form. Clouds that produce rain like nimbostratus and cumulonimbus are also common at warm fronts. Eventually, enough water vapor condenses upon pieces of dust, pollen or other condensation nuclei to form a cloud.
Water or various other chemicals may compose the droplets and crystals. The pouches are created when cold air within the cloud sinks down toward the Earth.Weather prediction: Severe weather might be on its way!

They are made of liquid water, but they don’t often produce rain.Weather prediction: Fair. They often grow into cumulonimbus clouds, which produce thunderstorms. Heated by sunshine, the ground heats the air just above it. They are still clouds, though, because they are made of water droplets condensed from the water vapor in the exhaust of the jet engines.Weather prediction: Contrails can provide information about the layers of moisture in the sky. Some clouds form as air warms up near the Earth's surface and rises. Air also can’t hold as much water when air pressure drops. The same occurs with thunderstorms. "As warm air is shot up into the atmosphere, it meets with colder air and condenses, i.e., it forms clouds and raindrops. Consequently, thunderstorms are usually followed by dense rain and cloudbursts," explains Silas Boye Nissen, a Ph.D. student at the Niels Bohr Institute, and one of the researchers behind the study. Clouds also form when air is forced upward at areas of low pressure. The vapor becomes small water droplets or ice crystals and a cloud is formed. When they accumulate in clusters, these storms are often accompanied by violent cloud bursts and flooding, which can devastate the areas affected.
Scientists use data from GOES-R series satellites, along with data from NASA's CloudSat Mission to study cloud properties.

This results in a self-reinforcing effect," explains Silas Boye Nissen, who concludes: "Torrential rain from cloud bursts often causes damage to homes and jeopardizes people's lives.
Orographic clouds get their shape from mountains or hills that force the air to move over or around them. As air rises it cools and decreases pressure, spreading out.
Clouds form from water or ice that has evaporated from Earth’s surface, or from plants that give off water and oxygen as a product of photosynthesis.
Some clouds, such as lenticular and stratus clouds, form when wind blows into the side of a mountain range or other terrain and is forced upward, higher in the atmosphere. Stratiform clouds have a more uniform, featureless appearance, and often cover the whole sky. Thunder occurs when warm, moist surface level air rises into weather and meets cooler air higher up in the atmosphere. As such, it is important to keep researching the causes of extreme weather phenomena.". You can be assured our editors closely monitor every feedback sent and will take appropriate actions.
