What was the contribution made by Vilhelm Bjerknes to meteorology?
Two years later he discovered the circulation theorems that led him to a synthesis of hydrodynamics and thermodynamics applicable to large-scale motions in the atmosphere and the ocean. This work ultimately resulted in the theory of air masses, which is essential to modern weather forecasting.
What did Vilhelm Bjerknes do?
Vilhelm Bjerknes is considered by many to be one of the founders of modern meteorology and weather forecasting. Born on March 14, 1862, in the Norwegian town of Christiania, Bjerknes was destined for a career in science.
What activity is associated with Vilhelm Bjerknes?
Vilhelm Bjerknes (1862-1951), a pioneer of modern meteorology, was especially known for his studies in hydrodynamics and thermodynamics and their relation to atmospheric motion.
Who Discovered air masses?
The term ‘air mass’ was introduced some 70 years ago by Norwegian meteorologists from Bergen, Norway.
Who developed the polar front theory?
Vilhelm Bjerknes
Members of the Bergen school, founded by Norwegian meteorologist and physicist Vilhelm Bjerknes, first proposed the concept of the polar front.
Where is the polar front?
Polar fronts are generally located poleward of 30° latitude in both hemispheres and occasionally extend to near the Arctic and Antarctic circles (66°30′ N and S).
Which air mass produces the most rain?
maritime Tropical
The maritime Tropical (mT) is the most important moisture-bearing and rain-producing air mass throughout the year. In winter it moves poleward and is cooled by the ground surface. Consequently, it is characterized by fog or low stratus or stratocumulus clouds, with drizzle and poor visibility.
What happens along a stationary front?
Because a stationary front marks the boundary between two air masses, there are often differences in air temperature and wind on opposite sides of it. The weather is often cloudy along a stationary front, and rain or snow often falls, especially if the front is in an area of low atmospheric pressure.
What happens along a polar front?
Polar front, in meteorology, the transition region separating warmer tropical air from colder polar air in the mid-latitudes.
What is an arctic cold front?
An Arctic Cold Front is a boundary between arctic and polar air masses. An Arctic air mass forms, when the air above a snow/ice covered surface cools down due to very low solar heating and strong heat emission from the surface. Consequently, it is only found above the polar ice areas.
