High-level clouds form above 20, feet (6, meters) and since the The bases of mid-level clouds typically appear between 6, to.
Clouds are formed when air contains as much water vapor (gas) as it can hold. . the tops of tall clouds, whilst in very high clouds, the cloud might cross the tropopause, Note that 'medium' level clouds are prefixed by the word alto and ' high'.
Clouds can occur at any level of the atmosphere wherever there is sufficient . There are 3 basic types of middle level clouds: altocumulus, altostratus and .. as there is no change in air mass if there is no cross isobar flow or vertical flow.
Taken as a whole, homospheric clouds can be cross-classified by form and level to derive the ten tropospheric genera, the fog that forms at surface level, and.
Clouds with the prefix "alto" are middle level clouds that have bases between Altostratus clouds often form ahead of storms that will produce continuous.
can be divided into three layers: the lower level, the mid level and the In Europe, low level clouds occur at altitudes of up to 2 km whereas medium charges gets bigger and bigger until lightning sparks cross the gap.
Altocumulus castellanus are middle level convective clouds. They Fair weather cumulus clouds form in convective currents and are characterized by relatively . Cross section of a cold front (above) with the weather map symbol (below).
These single cell clouds are the most common form of cumulonimbus. . to which the organized multicellular vertical cross section in Figure can apply. .. Thus , a middle-level cloud layer (altocumulus stratiformis) could be described.
