[Geography Notes] on Atmospheric Science Pdf for Exam

The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and forms its planetary atmosphere, and is held in place by gravity. The Earth’s atmosphere protects life on the planet by maintaining surface pressure that allows liquid water to remain, absorbing ultraviolet solar radiation, warming the surface through heat retention, and reducing temperature extremes between day and night.

Earth and Atmospheric Science

The study of the atmosphere and its various inner-working physical processes is known as atmospheric science. Meteorology is the study of the atmosphere’s chemistry and physics, with an emphasis on weather forecasting. Climatology is the study of long- and short-term atmospheric changes that characterize average climates and how they evolve as a result of natural and anthropogenic climate variability. The analysis of the upper layers of the atmosphere, where dissociation and ionization are significant, is known as aeronomy. The area of atmospheric science has been expanded to include planetary science and the study of the atmospheres of the solar system’s planets and natural satellites.

Experimental instruments used in atmospheric science include satellites, rocketsondes, radiosondes, weather balloons, and lasers.

Oceanic Sciences 

The mechanics, chemistry, and biology of marine environments are all covered by ocean sciences. Ocean circulation, energy dissipation, marine biology, ecology, biogeochemical cycles, water mass formation and movement, ocean temperature, and salinity, and marine carbon and carbonate chemistry are all topics covered in this area.

Atmospheric Scientist

Atmospheric scientists can work in nearly any area that has to do with the atmosphere. They are more than just meteorologists and weather forecasters; their credentials enable them to conduct research and analysis of the environment in the future, present, and past, ranging from major weather systems to minor impacts on other biological life.

What do Atmospheric Scientists do?

The word “atmospheric science” refers to anyone who studies the atmosphere of our earth. Although the topic includes meteorology (the study of weather), it is not the only aspect of it. Atmospheric scientists will examine the weather and forecast what it will be like in an hour, a day, a week, or the following season. An Atmospheric Scientist, for example, will have the experience to understand the mechanism that will lead to those two phenomena in the first place and will predict when they are supposed to occur, while a meteorologist will understand and predict the results. They’ll study regional trends and create a map of the overall scene, including the causes and effects.

They can work in public health, researching air quality and its effects. This is frequently unrelated to the weather. They may also be able to forecast long-term drought cycles and provide mitigation advice. Short-term weather is just a small part of this job, once again.

Meteorologists concentrate on the current, while atmospheric scientists look back at older data to create an image of past climate, weather, and atmospheric conditions. They are more likely to research historical data (paleoclimate data), such as tree ring information, to determine the composition of the atmosphere. They’ll look at chemistry, climatology, and the nature of weather systems on this planet and those in the solar system, as well as physics.

In India, there are various institutes which offer atmospheric science degrees to the students which are related to the field of earth and atmospheric sciences. Most jobs in atmospheric science include a bachelor’s degree in meteorology or a closely related earth science field. Atmospheric scientists need a master’s degree at the very least, but a Ph. D. is normally needed for research positions.

Atmospheric and Oceanic Sciences

Princeton University and the National Oceanic and Atmospheric Administration’s Geophysical Fluid Dynamics Laboratory (GFDL) collaborate on the Program of Atmospheric and Oceanic Sciences (AOS). Graduate students, postdoctoral researchers, visiting researchers, permanent research staff, and professors are all hosted by AOS, which is an independent program within the Department of Geosciences. 

Meteorology Programs

Meteorology is a branch of atmospheric science concerned primarily with weather processes and forecasting. The physical, dynamical (a force that causes change or motion), and chemical state of the Earth’s atmosphere, as well as interactions between the atmosphere and the Earth’s surface, are all studied in this area.

To pursue a career in meteorology, one must possess ample interests as well as a high level of education. Meteorologists have a variety of lucrative career options.
