It is very important to know what are the uses of rain water, since we can give it many uses and it is important for the environment and for the Earth's vegetation. We invite you to continue reading to learn a little more about rain.
Hydrological cycle
The heat of the sun causes a part of the water in the rivers, seas, oceans, lakes, to evaporate and begin to rise towards the atmosphere, in the atmosphere the water becomes clouds and then when it cools down it precipitates or falls in the form of rain, hail or snow.
Sometimes before it rains the sky lights up, that is when lightning strikes and then we hear the noise of thunder, the water that precipitates returns to the rivers, seas, oceans, lakes and thus the hydrological cycle is completed.
Clouds
They are a visible set of tiny water particles that float in the air, there are several types of clouds according to their shape, clouds can be cirrus, cumulus, stratus, nimbus and fog.
- Cirrus clouds: They are very high clouds in the form of white brushstrokes, they are the highest of all and make the weather change.
- The cumulus: They are high, white clouds in the shape of large cotton balls, usually signifying good weather.
- The strata: They are low clouds in the form of white stripes, they are the ones that produce rain or drizzle.
- The nimbuses: They are very dense low clouds that cover the dark gray sky, they are the clouds that produce rain.
- The fog: It is water vapor formed by very fine drops, it forms at ground level, especially at night and in the morning, as this type of cloud is so close to the ground, it is called mist.
relationship between wind and clouds
The wind is the air in movement in general, the wind moves from areas of high pressure to areas of low pressure, the winds blow in any direction horizontally, the breezes are light winds that blow from the sea to the land during the day and from the land to the sea during the night, the winds carry the clouds towards cold mountainous areas or up into the atmosphere, the clouds produce rain when they cool.
Rain water, drizzle and dew
They are forms of precipitation of rainwater contained in the clouds, the water can also fall in a solid state, in the form of snow or hail.
- rainwater: It is a form of liquid water precipitation that occurs when clouds cool. When the temperature in the clouds drops below zero degrees Celsius, the water droplets increase in size and weight, there comes a time when the drops become so heavy that they can no longer float and fall as rain.
- The drizzle: It is a small rain in very small drops, very close to each other that fall gently.
- Dew: It is the water vapor that with the temperature of the evening becomes like tiny drops, we can see the dew on the leaves of the plants and on the things that are on or near the ground.
rainwater feature
- Rainwater is pure as long as it is not produced by acid rainwater.
- It does not take a large amount of money to accumulate it.
- Rainwater can be stored and is free of charge.
- Rainwater is drinkable.
Relations between rain and rivers
The rivers are permanent and continuous streams of water that move in a field, when it rains in the mountainous areas the water penetrates the earth, it was coming out little by little and forms the streams and between several streams a river is formed.
The amount of water in a river depends on the amount of rain, this will also depend on the temperature in the air because when the surface of the land or the sea is heated by solar radiation, the energy that emanates from them is converted into vapor that makes the clouds are loaded with it.
In the atmosphere there are different factors that maintain the distribution of temperature, if these factors did not exist all the humidity of the earth would become air, on the other hand the amount of humidity contained in the air, the difference between the specific heat of the land and water determine important temperature variations within each of the five zones of homogeneous temperature distribution that exist on earth.
Due to this, a regulation of climates takes place in areas affected by marine currents such as gulfs, coasts or cold currents, another factor that influences air temperature is altitude, since its temperature decreases approximately one degree every hundred and eighty meters, so in mountainous areas there is a level above which there can always be snow.
How to purify rainwater?
Rainwater is pure, but at the same time it is not suitable for human consumption since it can cause stomach problems for some people, this is because rainwater comes from the clouds that absorb all the pollution on the planet.
For these to be suitable for human hydration, they must go through a filtration process, which not everyone knows how to carry out correctly, then we will indicate step by step how the process is carried out. Water Recycling of rain:
- Rainwater is channeled so that it falls into the same container.
- Install a filter that will absorb all the dirt that rainwater can bring with it.
- Through small pipes, another filter is connected to which chlorine is added, so that the water is purified.
- It is necessary that another filter is at a considerable height where the water can only reach through pumps.
- All pipes must be stainless steel.
- The water will be transported through pipes to a tank that will have a breather.
- Inside the house there must be an ozonator so that the water that comes out of it already has the amount of oxygen necessary for man to consume it.
Humidity
Air contains a certain amount of dissolved water vapor that varies according to temperature and local conditions, humidity can be expressed as follows:
absolute humidity
It is when the amount of water evaporation contained in a volume of air depending on the temperature, the air can contain a greater or lesser amount of humidity, hot air can dissolve a much higher amount of water evaporation than cold air, therefore absolute humidity does not give us an idea of the degree of saturation of the atmosphere.
saturation humidity
It is the maximum amount of water vapor that a volume of air can contain, so for example at zero degrees centigrade the air can only dissolve four grams with eight eighths per cubic meter of water vapor, while at thirty degrees centigrade it can contain up to thirty grams per cubic meter, therefore, the saturation humidity depends on the temperature, changes in air temperature give rise to rainwater.
Pressure
The air pressure is due to the weight of the atmosphere that is exerted on the surface of the earth, being at sea level equivalent to the pressure that a column of mercury seven hundred millimeters high, exerts on its base and varies with pressure. temperature, humidity and altitude.
When the air warms up it expands so its density decreases and the same amount of air occupies a larger volume, this causes low pressure zones or cyclonic areas to be produced in the atmosphere due to the heated acidic air and high pressure zones or areas anticyclonic in which there is cold and denser air.
The dense air of the anticyclonic zones will try to occupy the less dense or cyclonic air zones, thus establishing a movement in the air that receives the name of wind.
Storm
It is a violent disturbance of the atmosphere that occurs when two or more air masses of different temperatures meet in the same space, the physical effects of the storm are strong winds, rain, lightning and thunder.
In storms the sky turns dark and the wind can be so strong that it breaks branches of the trees, during storms electrical sparks are produced that violently detach from the clouds, these sparks are lightning, the very bright glow that is produced by The electrical discharge of lightning is called lightning and the very loud noise that occurs when there is an electrical discharge is called thunder.
Types of weather
It is designated by the expression weather, the state of the atmosphere at a given time.
Climate is the average state of the atmosphere throughout the year, a large number of climates that are established based on temperature and rainfall throughout the year, there are some Climate Characteristics, which in turn depend on the geographical location of the place considered.
The most characteristic climates are:
- Arid climates: Characterized by a highly irregular rainfall regime, since it may not rain for several years and at a given moment it rains so copiously that they cause floods, the temperature regime is likewise very variable, distinguishing between hot deserts and cold deserts, in the former the temperature during the During the day they are the highest on the planet, but during the night the descent is very pronounced.
In the frozen deserts there is a clearly delimited cold season, the amount of rain is also very scarce but not as irregular as in the hot deserts, the desert areas represent a quarter of the total land area of the planet.
- Tropical climate: Categorized by an annual average of twenty-five degrees Celsius and abundant rainfall, evenly distributed throughout the year, reaching two thousand millimeters of annual rainwater.
- Humid temperate climates: Within this general denomination there are some types, among which the Mediterranean climate and polar climate stand out.
- Mediterranean climate: They alternate a cool season with frequent rainwater in which the temperature ranges between five and ten centigrade and a dry season with temperatures of twenty to twenty-five degrees centigrade, with this the annual rainfall ranges between five hundred and eight hundred millimeters, this climate is given in the Mediterranean littoral zone and in some regions of South America and Africa.
The vegetation cover is discontinuous formed mainly by olive trees, oaks, pines and cypresses, due to the dry season the fluvial regime is discontinuous so they present a torrential regime with the consequent very intense erosive activity in this area.
-
- Sea environment: It is characterized by the influence of humid marine winds, which determine a damping of the annual degrees centigrade that fluctuate too much with mild winters and cold summers, the rains vary considerably from here to places where there is a beach, they can exceed two thousand five hundred millimeters per year. , while the general average can be established over eight hundred millimeters per year in Spain, the north of the peninsula has this environment.
- Polar climate: The maximum temperature in the sea with the highest temperatures does not reach ten degrees centigrade, and in winter the average temperature is between thirty and forty degrees centigrade below zero, the precipitations oscillate around three hundred millimeters, it heats up in such a way that it is generally accompanied by strong winds, vegetation is reduced to a minimum or absent.
acid rain water
Acid rain is an extreme and highly visible form of irreparable damage being done to the ozone layer.
In some areas of the planet such as northern Europe and its effects have been truly devastating, rainwater has ruined crops, forests and endangered the continuity of many plant and animal species in formation.
formation of acid rainwater
Acid rainwater generally originates in high clouds when sulfur and nitrogen oxides join with atmospheric vapor, producing sulfuric and nitric acids that are carried by winds long distances from their source elsewhere. In the form of rain, snow or fog, the origin of acid rainwater dates back to the beginning of the Industrial Revolution, more than two centuries ago. However, its worst consequences are those experienced in the XNUMXth century.
