Cirrus
Cirrus is a genus of atmospheric cloud generally characterized by thin, wispy strands, giving the type its name from the Latin word cirrus meaning a ringlet or curling lock of hair.
Cirrocumulus
Cirrocumulus is one of the three main genus-types of high-altitude tropospheric clouds, which also includes cirrus and cirrostratus. They usually occur at an altitude of 5 kilometres to 12 kilometres.
Cirrostratus
Cirrostratus cloud is a high, thin, generally uniform stratiform genus-type, composed of ice-crystals. It is difficult to detect and is capable of forming halos when the cloud takes the form of thin cirrostratus nebulosus.
Altocumulus
Altocumulus is a middle-altitude cloud genus that belongs to the stratocumuliformphysical category characterized by globular masses or rolls in layers or patches, the individual elements being larger and darker than those of cirrocumulusand smaller than those of stratocumulus
Altostratus
Altostratus is a middle altitude cloud genus belonging to the stratiform physical category characterized by a generally uniform gray to bluish-gray sheet or layer, lighter in color than nimbostratus and darker than high cirrostratus.
Stratocumulus
A stratocumulus cloud belongs to a genus-type of clouds characterized by large dark, rounded masses, usually in groups, lines, or waves, the individual elements being larger than those in altocumulus, and the whole being at a lower altitude, usually below 2,400 m (8,000 ft).
Nimbostratus
Nimbostratus is a low-to-middle altitude cloud that has considerable vertical and horizontal extent and produces precipitation over a wide area. "Nimbo" is from the Latin word "nimbus", which denotes precipitation.
Radiation Fog
Radiation fog is formed by the cooling of land after sunset by thermal radiation in calm conditions with clear sky.
Advection Fog
Advection fog occurs when moist air passes over a cool surface byadvection(wind) and is cooled.
Upslope Fog
Up-slope fog or hill fog forms when winds blow air up a slope(called orographic lift)adiabatically cooling it as it rises, and causing the moisture in it to condense
Evaporation Fog
This type of fog forms when sufficient water vapor is added to the air by evaporation and the moist air mixes with cooler, relatively drier air.
