In our atmosphere, there are dozens phenomena that keep happening round the year, which directly or indirectly affect us and decide our activities and life-style. However, all such activities are not independent form each other, but rather dependent on each other. Pressure belts are one such region that define and decide atmospheric activities on global scale. What are Meaning of Pressure Belt? Pressure belts define the region in the earth’s atmosphere where air pressure is relatively homogenous or uniform. Such regions usually characterized as either ‘Low’ or ‘High’ pressure belt. These pressure belts form due to the complex interactions ... Read More

Air mass is a very large envelop of air, which has usually homogenous characteristics in terms of temperature and humidity. However, when such a huge body of air moves it affect the weather patterns of the region where it goes. Secondly, when an air mass moves and counter another air mass; this phenomenon drastically affects the weather conditions. What is the Meaning of Interactions of Air Masses? When two air masses of different properties move in opposite directions and collide with each other, it forms ‘front’ (and the phenomenon is known as frontogenesis) and such conflicting phenomenon causes various ...

Very similar to blizzards, heatwaves are also complex and fatal winds that affect flora and fauna on large scale. However, in comparison to the blizzard, heatwaves are totally opposite in nature. Blizzard can be seen in temperate region during the winter time; whereas, heatwaves can be seen tropical and sub-tropical region during the summer. In blizzard, temperature always used to be much below to 00 C; on the contrary, in heatwaves, temperature remains 400+. Moreover, one is cold and other one is hot, but both are dangerous for humans and humans’ activities. What is Heatwave? As defined by ... Read More

During the winter morning, more often we face visibility issue and as the sun’s rays get intense, environment becomes clear and visible. It happens because of fog. Fog is general phenomenon that usually occurs during the winter time. So, in this article, we will discuss the meaning, formation, and types of fog. What is Fog?

Coastal plain is one of the notable geographical features that covers vast land area at the sea or ocean coast. Such extensive region formed over millions of years and hence holds immense ecological significance. In terms of not only attractive landscape, but also in terms of ecological and economic values, coastal plain has various role to play. What Exactly Coastal Plain is? Coastal plain is a low-lying area, which has flat or very gentle slope, located along the coastline of respective country. It extends from the shoreline to higher elevation terrains. It has noticeable features like sandy ... Read More

Earth’s atmosphere is full of mystery; there are dozens of phenomena that keep happening all the year. One of such phenomena is clear-air turbulence. It is mysterious and invisible phenomenon of air mass that potential enough to obstruct the path of aircraft. What is Meaning of Clear-Air Turbulence? Also known as "invisible turbulence" or "atmospheric turbulence, " Clear-Air Turbulence (CAT), describes the turbulent air movements (air mass) that occur in higher atmosphere or in high altitudes. This region is total calm and cloudless and absence of any other dust particles. Because of such reason, the movement of air ... Read More

An air mass is a huge envelop of air, which has relatively homogenous properties in terms of temperature, humidity, and stability. The length of this air mass sometimes measured even thousands of kilometers and width measured as hundreds of kilometers. Such a huge body of air significantly affect the respective weather system. Interestingly, based on its place of origin and its properties, air mass is classified into various types. In this article, we will discuss the different types of air mass along with their properties. Classification of Air Mass Primarily, air mass is classified on the basis of its ... Read More

Usually found in the freezing cold regions, cirque is one of the nature’s wonders that attracts people from remote regions.
