Not all clouds are created equal.

Stratus clouds are low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds that are formed by rising thermals. More specifically, the term stratus is used to describe flat, hazy , featureless clouds at low altitudes varying in color from dark gray to nearly white. These clouds are essentially above-ground fog formed either through the lifting of morning fog or through cold air moving at low altitudes over a region. Some call these clouds "high fog" for their fog-like form. While light rain may fall, this cloud does not indicate much meteorological precipitation.

Types Of Clouds And What They Mean

Choose the best vocabulary word for each sentence and write it in the blank. Relative humidity refers to the percentage of water vapor in the air at a specific temperature compared to the amount it could hold. Water vapor is a gas. You can t swim in water that is in this form. Water vapor, which helps create clouds, gets into the air by means of evaporation.

The bottoms of clouds show us where the dew point has been reached. When clouds rest on the ground, they are known as fog. Rain, snow, sleet, and hail are all types of, precipitation which comes from some but not all kinds of clouds. Proverbs and poems are two different types of writing that people can use to express themselves creatively. A proverb always teaches a lesson and can be a catchy way to memorize a rule.

A poem can do these things, too, but it can also just be a creative way of talking about the world and your experiences in it. Many poems rhyme, but not all. On a separate sheet of paper, write a proverb about a weather observation you have made, and then write a poem about clouds. Share your writing with the rest of the class. Depending on the ability level of the class, additional instructions may be useful before assigning this exercise.

For example, you may wish to specify length, meter, rhyme scheme, or a specific style, such as a haiku. Answers will vary and should be primarily graded based on the observations made for proverbs and on the creativity of the poetry. They are made up of ice crystals and float in the chilly air more than four miles above you.

The name for these wispylooking clouds comes from the Latin word for curl. Some people call them mare s tails. Layered but puffy clouds that occur at middle and lower elevations. Thick, puffy clouds that can be found at middle altitudes. Low-lying clouds that are generally producers of rain and snow Cirrocumulus Cumulonimbus Small cottony rows of cloud tufts that are made of ice crystals and found at high elevations.

The big rain cloud, part of its name means clouds, signifying rain to the ancient Romans. These clouds can rise to heights of more than 50, feet. When their tops reach the fast-moving jet stream, they become cirrus-like and are called anvil heads. Some people also call these clouds thunderheads, because they can bring heavy rain, lightning, and thunder.

Stratus The lowest clouds, they hang like a ceiling at less than 6, feet. Their name comes from the Latin word to spread, as in layers. These clouds appear as a general overcast and can produce widespread rain and snow. Altostratus Wispy clouds that are found at middle elevations. Cumulus Clouds of vertical development, they get their name from the Latin word for pile or heap.

The lowest are the puffy clouds of a summer day. Cirrostratus Wispy, thin sheets of clouds that are made of ice crystals and found spreading at high elevations. On the thermometer, the bigger numbers on the outside circle indicate degrees Fahrenheit; the smaller numbers inside indicate degrees Celsius.

When the temperature is 32 degrees Fahrenheit, what is the temperature in degrees Celsius? What do you know about this temperature? When the temperature is 32 degrees Fahrenheit, we know it is also 0 degrees Celsius. This is the temperature at which water freezes. What is the temperature on the thermometer below in degrees Fahrenheit?

It is approximately 60 degrees Fahrenheit, or 15 degrees Celsius. Accept all answers that are close to these values. Your Canadian pen pal writes you a letter in July and tells you that the temperature where she lives has already reached 35 degrees Celsius. What is the equivalent temperature in degrees Fahrenheit?

Would you expect that kind of temperature in July? Why or why not? The equivalent temperature is 95 degrees Fahrenheit. Answers will vary depending on location. What is the temperature outside today in degrees Celsius?

Answers will vary. It s 5 degrees Celsius outside. What is the approximate temperature in degrees Fahrenheit? Should you dress for warm or cold weather? When it s 5 degrees Celsius outside, it is approximately 40 degrees Fahrenheit.

You should dress for cold weather because the temperature is near the freezing point One winter morning, you look out the window and see a dark nimbostratus cloud blanketing the sky. Then, you turn on the radio and the weather forecaster tells you to expect rain, sleet, and snow all day and a high temperature of 40 degrees Celsius. Which piece of information in this forecast seems wrong?

The temperature 40 degrees Celsius is incorrect and maybe just the word Celsius. Also, since a nimbostratus cloud is outside and we know that nimbostratus clouds generally are producers of rain and snow, the other information is likely to be correct.

Remember that it s important to consider a cloud s altitude, or height above ground, when identifying cloud types. In addition, think about the word origin worksheet you just completed. Use the Latin meanings in the clouds names to figure out what they look like or where they are located in the picture.

Cirrus 2. Cirrostratus 3. Cirrocumulus 4. Altocumulus 5. Stratus 8. Nimbostratus 9. Cumulus Latin originated more than 2, years ago in ancient Rome and was the primary written language of western Europe for hundreds of years, until about years ago when people began using their own local languages for writing. But even then, Latin continued to be used as the language of scientists and scholars for another years.

As you might imagine, the words of a language used for so long and by so many people would creep into many languages. In fact, about half of the words in the English language are of Latin origin.

Let s take a closer look at how Latin and English words are related. Our word nimbostratus as in the nimbostratus cloud for example, is made up of two Latin words. To find out exactly what a nimbostratus cloud is, we can break apart the word into its Latin parts. In Latin, nimbus means cloud, which signified rain and water to the ancient Romans. Stratus means to spread, as in layers. If we put these two meanings together, we might reason that a nimbostratus cloud is a gray rain cloud that spreads across the sky as a general overcast.

In fact, our guess is right on target. Nimbostratus clouds are low-lying clouds that are generally producers of rain and snow. Latin words can be found in many of the names of the cloud types you are studying. First, look up the five Latin words below in the dictionary and write the meaning next to each word. Then, using the Cloud Bank at the right, write the names of the clouds that use the Latin root word s in them. Remember: Each Latin word will have more than one cloud type next to it.

Some of the cloud types may be used twice. What is evaporation? Evaporation is the process by which molecules convert from liquid form to gas. Evaporation of water occurs when water reaches its boiling point. Define dew point. The dew point is the temperature at which water vapor in the air converts to water droplets. These droplets attach to dust particles in the air and form clouds. In addition, they can attach to objects on the ground and form dew.

What is relative humidity? How can it be increased? Relative humidity is the percentage of water vapor in the air at a certain temperature compared to the amount it could hold. Since relative humidity is dependent both on temperature and vapor levels, it can be increased by 1 adding more moisture to the air or by 2 decreasing the temperature, since air at lower temperatures holds less moisture.

What are clouds made of? How high off the ground are they?

News, analysis, experiments, videos, games, and educational paths on the issues of energy and the environment for complete and topical information. Howard, in , and the classification system that he proposed is, with some modifications, still used today. It is based on two principal groups, divided according to the development vertical and horizontal and three types: cirrus, cumulus and stratus clouds. The different combinations of groups and types lead to the different cloud formations. They seem to cover the sky in a uniform manner at various levels.

What is Cloud, Study Notes on Types of Cloud: Physical Geography

How Clouds Form : Clouds form when water vapor water that has evaporated from the surface of the Earth condenses turns into liquid water or solid ice onto microscopic dust particles or other tiny particles floating in the air. This condensation cloud formation happens when warm and cold air meet, when warm air rises up the side of a mountain and cools as it rises, and when warm air flows over a colder area, like a cool body of water. This occurs because cool air can hold less water vapor than warm air, and excess water condenses into either liquid or ice.

Not all clouds are created equal. The different types of clouds are named based on their shape and how high up they hover in the troposphere. For instance, the diagram below provides a quick overview of the most common types of clouds based on altitude.

Cirrocumulus cloud

In a companion paper Golaz et al. The model represents the subgrid-scale variability of vertical velocity, temperature, and moisture by use of a joint probability density function PDF. The PDF is selected from a predetermined family for each grid box and time step, thereby allowing the PDF to vary in space and evolve in time. The family of PDFs employed is the three-dimensional analytic double Gaussian 1 family proposed by Larson et al. This family was tested against aircraft measurements and output from large eddy simulation LES models.

Cirrocumulus is one of the three main genus-types of high-altitude tropospheric clouds, the other two being cirrus and cirrostratus. Like lower-altitude cumuliform and stratocumuliform clouds, cirrocumulus signifies convection. Unlike other high-altitude tropospheric clouds like cirrus and cirrostratus, cirrocumulus includes a small amount of liquid water droplets, although these are in a supercooled state. Ice crystals are the predominant component, and typically, the ice crystals cause the supercooled water drops in the cloud to rapidly freeze, transforming the cirrocumulus into cirrostratus. This process can also produce precipitation in the form of a virga consisting of ice or snow.

What Are Clouds?

Melanie has a BS in physical science and is in grad school for analytics and modeling. Clouds are large groups of tiny water droplets vapor or ice crystals that cling to pieces of dust in the atmosphere. Clouds are so important to the earth's weather that meteorologists people who study the weather also study the clouds and their movement. In fact, without clouds, it wouldn't rain or snow! They come in all different shapes and sizes.

Choose the best vocabulary word for each sentence and write it in the blank. Relative humidity refers to the percentage of water vapor in the air at a specific temperature compared to the amount it could hold. Water vapor is a gas.

Они знают, как отсюда выбраться. На перекрестке он свернул вправо, улица стала пошире. Со всех сторон открывались ворота, и люди вливались в поток. Колокола звонили где-то совсем рядом, очень громко. Беккер чувствовал жжение в боку, но кровотечение прекратилось. Он старался двигаться быстрее, знал, что где-то позади идет человек с пистолетом.

Stratus cloud

Но Стратмор ее не слышал. Его жизнь окончена. Тридцать лет отдал он служению своей стране.

Если Танкадо убьют, этот человек опубликует пароль. - Его партнер опубликует ключ? - недоуменно переспросила Сьюзан. Стратмор кивнул: - Он разместит его в Интернете, напечатает в газетах, на рекламных щитах.

Сьюзан задумалась. Она чувствовала, что здесь что-то не то, но не могла сообразить, что. Она достаточно хорошо знала Танкадо и знала, что он боготворил простоту. Его доказательства, его программы всегда отличали кристальная ясность и законченность.

Визит вылился в сплошной пиар и бесчисленные интеллектуальные тесты при минимуме информации по существу дела. Через неделю Сьюзан и еще шестерых пригласили. Сьюзан заколебалась, но все же поехала.
