Moses entered the cloud and went up on the mountain. The two main type of mid-level clouds are altostratus and altocumulus. But how does the water and ice that makes up clouds get into the sky? Altocumulus clouds exhibit "cumulo" type characteristics (see below) in mid levels, i.e., heap-like clouds with convective elements. Depending on the altitude, time of year, and vertical temperature structure of the troposphere, these clouds may be composed of liquid water droplets, ice crystals, or a combination of the two, including supercooled droplets (i.e., liquid droplets whose temperatures are below freezing). If enough atmospheric instability, moisture, and lift are present, then strong updrafts can develop in the cumulus cloud leading to a mature, deep cumulonimbus cloud, i.e., a thunderstorm producing heavy rain. Low clouds occur below 6500 feet, and normally consist of liquid water droplets or even supercooled droplets, except during cold winter storms when ice crystals (and snow) comprise much of the clouds. Submit a Storm Report At a warm front, where a warm air mass slides above a cold air mass, the warm air is pushed upward forming many different types of clouds – from low stratus clouds to midlevel altocumulus and altostratus clouds, to high cirrus, cirrocumulus and cirrostratus clouds. Lexington, Ky                                                 Jeffersontown, Ky.

University Corporation for Atmospheric Research, Visit us on Facebook These clouds appear frequently in the atmosphere, either ahead of or behind a frontal system. Due to cold tropospheric temperatures at these levels, the clouds primarily are, and often appear thin, streaky, and white (although a, low sun angle, e.g., near sunset, can create an array. Regional Weather Map Altostratus clouds are "strato" type clouds (see below) that possess a flat and uniform type texture in the mid levels. All types of clouds are formed by these processes, especially altocumulus, altostratus, cirrocumulus, stratocumulus, or stratus clouds. Low stratus decks are common in winter in the Ohio Valley, especially behind a storm system when cold, dismal, gray weather can linger for several hours or even a day or two. Clouds form when the air cools below the dewpoint, and the air can not hold as much water vapor. Louisville, KY6201 Theiler LaneLouisville, KY 40229-1476502-969-8842Comments?

Outreach low-level clouds, as well as a number of other interesting If enough atmospheric instability, moisture, and lift are present, then strong updrafts can develop in the cumulus cloud leading to a mature, deep. Hourly Observations As a warm front approaches, cirrus clouds tend to thicken into cirrostratus, which may, in turn, thicken and lower into altostratus, stratus, and even nimbostratus. Weather and Science for Kids: A lesson on trees losing their leaves in Winter! Jackson Mammatus most often are seen hanging from the anvil of a severe thunderstorm, but do not produce severe weather.

CoCoRaHS LMK Warning Area Stratocumulus clouds are hybrids of layered stratus and cellular cumulus, i.e., individual cloud elements, characteristic of cumulo type clouds, clumped together in a continuous distribution, characteristic of strato type clouds. Although often appearing ominous, shelf clouds normally do not produce tornadoes. Clouds are classified according to their height above and appearance (texture) from the ground. .

And on the seventh day he called to Moses out of the midst of the cloud. Finally, cirrocumulus clouds are layered clouds permeated with small cumuliform lumpiness. This can also happen without a dramatic mountain range, just when air travels over land that slopes upward and is forced to rise. 1-Stop Drought The vapor becomes small water droplets or ice crystals and a cloud is formed.
