What does a shower mean? The difference between a shower and a light rain.

Lead: In rainy season, it is easy to rain, sometimes it is a shower, sometimes it is a rainstorm, which will make passers-by unprepared. So, what does a shower mean? What's the difference between a shower and a light rain?

What does a shower mean?

Shower refers to the rain that lasts for a short time, suddenly starts and ends, and the precipitation intensity changes greatly. Sometimes accompanied by lightning and thunder, mostly in summer. Showers are intermittent, generally small in scope, with rain banners and often accompanied by strong winds.

Shower features:

1, showers mostly occur in summer when the temperature is high, and also occur from time to time in other three seasons;

2, the rainfall is uncertain, coming fast, going fast, and the rain is short;

3. Time is discontinuous, coming and going quickly, or sometimes not;

4. Discontinuity in space and uneven distribution in scope;

5. Discontinuous intensity and long time.

The difference between shower and light rain

The rainfall is different, and there is more rain under showers.

As a "light rain" in daily spoken language, it means "light rain". Generally speaking, raindrops are clearly visible and don't float, the ground doesn't splash, the water in the depression is slow, the rain in the house is weak, and the eaves drip, so you can walk a short distance in the rain without an umbrella, and your clothes won't get wet.

Precipitation is a key physical process connecting weather, climate and water cycle, and it is also the ultimate source of clean water to support ecosystem and human survival. It is extremely important for meteorology and climatology to study the change and prediction of precipitation. In precipitation research, precipitation, precipitation intensity and precipitation frequency are the main research aspects.

In recent years, the precipitation in China has the characteristics of flooding in the south and drought in the north, and the precipitation intensity has an increasing trend, but the annual precipitation frequency has a consistent decreasing trend, and drought and flood events have increased at the same time. On average, small-scale precipitation mainly depends on the change of rainfall days, and annual precipitation, seasonal precipitation and monthly precipitation all conform to this law. In previous studies, people paid more attention to the extremely strong precipitation that easily caused floods, but paid less attention to the light rain.

In most parts of China, especially in the north, the sum of light rain and moderate rain accounts for more than 60% of the annual precipitation, and the significant reduction of micro-precipitation events has been reflected in the drought in the north. The decrease of light rain frequency is the main reason for the decrease of precipitation frequency.

What is the difference between a thunderstorm and a shower?

1, different seasons

Thundershowers: Thundershowers generally occur in summer in China, mostly in the south of the Yangtze River in spring and autumn, and there are fewer opportunities for thunderstorms in winter or after 10. Thunderstorms are usually characterized by lightning and thunder, mixed with wind and rain, and come and go quickly. There are usually strong winds and trees when you come.

Shower: Shower is usually a sudden rain in sunny summer. Showers usually cover a wide area, and the flow is unpredictable, and the raindrops are correspondingly large and last for a long time.

2, the difference between discharge

Shower is a short period of cold air movement, and then cooled down, formed. It can be completed in a short time, and the clouds are not moving violently.

Thunderstorms also have large-scale cloud movements, which are much stronger than showers. Accompanied by discharge phenomenon.

3. Different definitions

Thunderstorm is a shower phenomenon accompanied by lightning. Produced under thunderstorm cumulonimbus clouds. It is characterized by large-scale cloud movement, which is much more violent than showers and accompanied by discharge, and is common in summer.

Showers, falling from cumulonimbus clouds, are short-lasting, suddenly start and end, and the precipitation intensity changes greatly. Sometimes accompanied by lightning and thunder, mostly in summer. Showers are intermittent, generally small in scope, with rain banners and often accompanied by strong winds.

4. Different characteristics

Judging from the time of day, thunderstorms mostly occur in the afternoon and evening. There are more opportunities on land when the thermal convection is strong in summer afternoon, forming a "thermal thunderstorm". At sea, thunderstorms often occur at night because of the slow cooling of the sea surface and unstable air at night. Thunderstorms near the front can occur simultaneously. In mountainous areas, topographic precipitation can occur.

Thunderstorms are usually paroxysmal, and there are often strong winds. Sometimes accompanied by tornadoes and hail. Persistent and intense thunderstorms can often reach the level of heavy rain. The most active areas of thunderstorms in the world are the tropics and mountains. There are 75- 100 thunderstorm days in the tropics, 20-50 thunderstorm days in the middle latitudes, only a few thunderstorm days in the polar regions, and there are no thunderstorms all the year round north of 82 degrees north latitude.

Showers mostly occur in summer when the temperature is high, and also occur from time to time in other three seasons. The rainfall is uncertain, and it comes and goes quickly, and the intermittent time of rain is short, and it comes and goes quickly, or sometimes it doesn't fall; Space is discontinuous, that is, the range distribution is uneven, the intensity is discontinuous, and the hour is large.

5, the intensity is different

Thunderstorms are much more violent than showers, accompanied by electric discharge. There are often strong winds and thunderstorms before coming. The wind came, flying sand and stones, overturning roofs and blowing down walls. In the storm, things in the street danced with the wind, flying everywhere and even uprooting trees.
