What is the Weather?

What Does Clima Mean

We explain what the climate is and what types of climate exist. Also, what are the elements and factors of the weather. Atmospheric weather.

The various geographical regions of the world have an associated climate.

What is the weather?

Climate refers to the patterns of variation in temperature , humidity , atmospheric pressure, wind, precipitation and other meteorological conditions of interest in a given geographic region . Climate is usually distinguished from time , since by the former the long-term conditions in the region are understood, while by the latter, its state in a short period of time .



The various geographical regions of the world have a climate associated and determined by physical factors and relationships between them, in what is known as the climate system , since they operate in an orderly and reciprocal manner, even in cases of extreme climates. Every climate system is made up of five layers of interaction: atmosphere , hydrosphere , cryosphere, lithosphere, and biosphere , each with particular chemical and physical characteristics.

At the same time, the climate can be studied from historical perspectives (paleoclimate) to understand the formation processes of our planet , including the origin of life ; or from projective perspectives, to make predictions and understand the processes currently in place in environmental matters.

Climate is an important factor in the planning of human activities , especially those that require specific and anticipated environmental conditions, such as agriculture . That is why the alterations of climate change and global warming can be so harmful to human life.

Types of weather

In the mountain climate the temperatures are very cold.

There are many technical ways of classifying climates, using various scales and with specific applications in the study of matter . However, the simplest classification of all is the one that attends to the degree of heat of the climate in question, and distinguishes between three possibilities:

  • Warm climates Those that present higher temperatures more constantly, such as equatorial, tropical, arid subtropical, and desert and semi-desert climates.
  • Temperate climates. Intermediate instance between hot and cold, with important variations according to the season and a lot of meteorological variability. Such as the humid subtropical climate, the Mediterranean, the oceanic and the continental.
  • Cold climates. Those in which low temperatures predominate throughout the year, such as polar climates, mountain or tundra climates .

Weather elements

Every climate is made up of a series of elements that are usually measured or evaluated by climatologists to make predictions. These are:

  • Atmospheric temperature It is the degree of heat or cold that exists in the atmospheric air masses , heated mainly by solar radiation.
  • Atmospheric pressure. It is the pressure exerted in all directions by the mass of air in the atmosphere , which has a huge impact on other climatic elements.
  • Winds. The pressure variations in the air generate displacements of the gaseous mass that we know as wind, and that allow the distribution of energy and heat in the atmosphere in a more equitable way.
  • Humidity . It is the degree of water in a gaseous state that is present in the gases of the atmosphere, a state that it reaches during its water cycle , when it evaporates.
  • Precipitation. The abundance of water vapor in the atmosphere leads it to condense in the form of clouds, which, when displaced by the wind, collide with each other and release their liquid content, in what we know as rain.

Climate factors

The mountains are a clear example of relief.

The climate is determined by the interaction of various factors, such as:

  • Latitude . The geographical location of the region whose climate is studied has a huge influence on air temperature and the incidence of solar rays, which explains the variation of the seasons and other climatic cycles.
  • Altitude . The level of meters above sea level at which a region is, will affect the atmospheric pressure and atmospheric temperature variables that it presents, according to the rule that states: the higher the altitude, the lower the temperature and the lower pressure.
  • Distance to the sea. The proximity or remoteness of the coast or of large bodies of water such as important lakes or large rivers, largely determines the humidity present in the air of a region.
  • Ocean currents. The movements of oceanic waters redistribute the masses of water on the planet and keep them moving , allowing warm and cold waters to alternate their position and cyclically affect the atmosphere, providing heat or cold as the case may be.
  • Relief . The orientation of the geological shape of the earth's surface can make a region more prone to drought or humidity, as in the case of mountains, for example: by stopping the humid winds coming from the coast, they absorb the humidity and generate dry winds from the other side.
  • Direction of the winds. The atmospheric air mass is often displaced, allowing hot and cold airs to offset their effect according to factors such as pressure, geography , etc. The action of the winds is key in the climate.

Atmospheric weather

Atmospheric time is known as the physical characteristics of the atmosphere at a given moment , specifically in the troposphere, where most atmospheric phenomena occur . Thus, the temperature, humidity, cloudiness and degree of movement of the atmosphere are measured, from which it is possible to better understand the climate dynamics of the planet.
