Meteorology is the scientific discipline that studies the planet’s atmospheric phenomena. Within the meteorological framework and all its variables, cold climates (also known as glacial climates) are those with very low temperatures or less than zero degrees. Cold Climates
As the cold concept is usually relative, a measurement unit called frigory is used to establish this condition. Through it, it is possible to determine the absence of heat in a certain area.
In addition to temperature, there are other variables that determine the concept of cold weather
The location of the studied planet is a determining factor for any climatic aspect. There are two particularly cold habitats: the polar zones and the high mountains. Thus, the further away from the tropics, the lower the average temperature. Cold Climates
This is because the sun’s rays have a lower incidence on the poles. Height is also decisive, as the greater the height, the smaller the temperature record. The distance of a territory in relation to the sea also affects the climate, because when we are distant from the sea the drop in temperature is higher. Wind and snow are other characteristics associated with cold climates.
Cold climates have consequences on human life
In places where temperature records are extremely low (called polar cold) conditions for a life in society are very difficult because they are areas with density of population very low.
The characteristic vegetation of territories with cold climates is the tundra, typical of the northern hemisphere of the planet. It is formed by mosses and lichens, and the subsoil remains frozen throughout the year. Below this latitude the climate is cold, but not to the extreme and the vegetation acquires greater variety (known as taiga).
The cold climate of the polar zones generates layers of ice on the sea, known as ice floes
The arctic ice floe is permanent, while the Antarctic ice is formed in winter and disappears during the short austral summer. Due to the climate change suffered by the planet, these ice areas gradually reduce and this circumstance has effects on the food chain of this ecosystem. The consequences are several: the danger of the extinction of some species (for example, polar bears) and especially with the reduction of ice floes, climate change is even worse.
