scientists have traditionally divided the clouds into warm and cold, ieavailable at positive and negative temperatures.Warm clouds are like fog and consists of microscopic water droplets.As for the cold clouds, according to traditional views, they may contain supercooled water droplets or ice crystals and a first and a second at a time, ie,are mixed in phase.

In theory, when a droplet in a cloud of ice crystals, immediately begins the process of Bergeron-Findayzena characteriz
ed recondensation or phase distillation.Simply put, the vapor condenses into ice.From this it follows that the two-phase cloud exist long incapable.In a few minutes it turns into a stable crystalline state.However, studies of the outstanding scientist AMBorovikova showed that under natural conditions, compound or spray cold clouds are more common and there are a lot longer than that predicted by the theory, laboratory practice or shows.

in a median strip and the most frequent are stable stratus clouds.They give and the largest amount of precipitation.Modern research has shown that virtually all cold clouds are mixed, iecontain both supercooled water droplets and ice crystals.

The structure they are divided into three basic types.The first structural type of cold clouds are traditionally considered water.Studies have shown that they contain ice crystals are not distinguishable by conventional methods - their sizes less than 20 microns.Two other types of clouds are called ldosoderzhaschimi.One type is characterized by the presence of relatively large ice crystals that are larger than 200 microns.This is usually translucent cloud structures located at high altitude and are not always visible from the ground.

Another type ldosoderzhaschih clouds characterized by the presence of pieces of ice, the size of which is less than 20 microns.It is dense, opaque structure that looks a little different from the cold water and warm clouds.They often bring precipitation in the form of snow or rain, depending on the temperature of the near-earth air layer.

presence of supercooled droplets of liquid at temperatures below -40 ° C, because in the real world of cloud structures, water changes its physical and chemical properties.The volatility of water compared to conventional conditions, increases by 5 times.This water evaporates and condenses much faster than usual.
