Chubascos: What are they and how they form

A shower is a type of precipitation that occurs suddenlypresents one Great intensity and short duration. Generally, they occur in liquid form, but according to atmospheric conditions they can include hail (hailstorm) or snow (snowfall) and are usually accompanied by a Subsco Temperature and Strong Winds.

Here you can read to know the hail better: what it is, how it is formed and types.

• Sudden intensity: Chubascos are characterized by a sudden increase in rain intensity. Precipitation goes from being scarce or non -existent to being abundant in a short period of time.
• Short duration: Chubascos are short -lived rain events. Usually, they last less than 30 minutes, although their duration may vary according to atmospheric conditions.
• Abundant precipitation: During a shower the amount of rain that falls can be significant in a short time, which often results in rapid accumulations of water in streets and low areas.
• Changes in time: Chubascos are often associated with the arrival of a mass of cold air or an atmospheric disturbance. They can be followed by improvements in weather conditions.
• Possible electrical activity: In some cases, showers can be accompanied by thunderstorms with lightning and thunder.
• Located and variable: Chubascos can be quite located and variable in their distribution. The affected geographical area is usually limited and leave nearby areas without rain. When we heard meteorologists speak and refer to “scattered showers” they refer to the fact that the showers are not uniform or continuously distributed in a region, but appear in locations and variable moments.

1. Atmospheric instability: A shower originates when there is an unstable atmosphere, that is, when the heating of a relatively reduced region of the earth’s surface is produced, which makes the warmest and less dense air masses tend to rise.
2. Training of vertical development clouds: As hot and humid air rises rapidly, it forms vertical development clouds known as cumulonimbus. These clouds are known for their great height and strong vertical ascent. Here you can read about how clouds are formed.
3. Convection: The formation of a shower involves a convection process that begins with the rise of hot and humid air inside a cumulonimbus cloud. This rise of the air triggers a feedback that further accelerates heat transfer carried out by cloud mass. This feedback is manifested through the descent of very cold and dry air from the top of the cumulonimbus down and around the cloud. It is precisely this cold and dry air that drives and reinforces the convection process.
4. Formation of rain drops: When the hot air rises, cools, and the humidity present in the air is condensed, small drops of rain or ice crystals are formed. These particles can merge with each other, giving rise to the formation of larger water drops.
5. Rapid descent from precipitation: As the rain drops become large enough, they fall quickly from the cloud to the surface of the earth. This results in an intense and sudden precipitation, which characterizes a show.

In summary, a shower is formed as a result of a convection process driven by atmospheric instability, with the rise of hot and humid air, the formation of vertical development clouds, positive feedback that accelerates convection, and the subsequent decrease in cold and dry air that amplifies the phenomenon, which results in intense precipitation and short duration.

• Intensity and duration: The rain is generally a continuous precipitation that can last hours and even days. The intensity of the rain is relatively constant and does not experience sudden changes during its duration. On the contrary, a show, it is an intense and sudden rain that usually lasts a short period of time and its intensity is usually high.
• Precipitation form: The rain is presented in liquid form and falls in the form of drops of water, on the other hand, a showpiece can occur in liquid form, hail or snow, depending on the climatic conditions and the season of the year.
• Cause and Training: A shower is produced through a convection process in vertical development clouds called cumulonimbus while the rain can occur not only by convection, when climbing the masses of hot air, cooled and condensing (convective rains) but by the clash of air masses with mountainous reliefs (orographic rains) or by the contact of two air masses of different thermal characteristics frontal). In addition, rain can be generated in different types of clouds such as nimboestrates or cumulonimbos.
• Geographic distribution: The rain can be more uniform and spread over a broader region, covering a considerable area. Contrary, showers are usually more located, affecting smaller areas and leaving nearby areas without rain.
