Oclimate, as we already know, it is the result of successive meteorological occurrences over time. It is about the behavior of the atmosphere. It is made up of some elements that dictate its characteristics, that is, they shape the different types of climate that exist all over the world.
You climatic elements, as the name implies, are the phenomena that make up the climate. They are: the temperature, a air humidity, atmospheric pressure and solar radiation.
THEtemperatureis the record of atmospheric heat and is usually measured in degrees Celsius (ºC) or in other units that are used in other countries, such as Fahrenheit (ºF) and Kelvin (K). Thus, a high temperature value – 37°C or 40°C, for example – means it is too hot, while lower temperatures mean it is colder.
THEair humidityis the amount of water present in the atmospheric air in the form of vapor. It is divided intoabsolute humidity, which is the total amount of water in the air, and relative humidity, which is the moisture of water present in the air compared to what is needed to start raining.
THEatmospheric pressureit is the “weight” that the atmosphere exerts on our heads and on the earth's surface, being measured in millibars (mb) or other units of measurement. Generally, when some climatic factor causes an increase in atmospheric pressure, temperatures get higher.
THEsolar radiation it is the heat produced by the sun and received by the Earth. It is very important to keep our planet warm and thus to control temperatures to support life. However, not all radiation received by our planet reaches the surface, most is absorbed or reflected by the atmosphere.
As our planet has a certain inclination on its axis, not all parts of the Earth's surface receive the same amount of solar radiation, which allows for so-called Earth's thermal zones. The process of reflecting solar radiation from the surface to the atmosphere and from the atmosphere back to the surface is calledgreenhouse effect.
As we can see, the climatic elements form the basic attributes that constitute the climate of different parts of the world. The presence or absence of these elements is conditioned to several other phenomena, called Climatic factors, which include relief, vegetation, altitude and others.
