What is Atmospheric physics: Definition and 16 Discussions

Within the atmospheric sciences, atmospheric physics is the application of physics to the study of the atmosphere. Atmospheric physicists attempt to model Earth's atmosphere and the atmospheres of the other planets using fluid flow equations, chemical models, radiation budget, and energy transfer processes in the atmosphere (as well as how these tie into boundary systems such as the oceans). In order to model weather systems, atmospheric physicists employ elements of scattering theory, wave propagation models, cloud physics, statistical mechanics and spatial statistics which are highly mathematical and related to physics. It has close links to meteorology and climatology and also covers the design and construction of instruments for studying the atmosphere and the interpretation of the data they provide, including remote sensing instruments. At the dawn of the space age and the introduction of sounding rockets, aeronomy became a subdiscipline concerning the upper layers of the atmosphere, where dissociation and ionization are important.

    I What are the most energetic lightning "superbolts" ever measured?

    Hi! I would be interested in properly referenced data about the most powerful / energetic lightning bolts on Earth to get a good idea about their maximum possible order of magnitude (maybe depending on location?) Both direct measurements or indirect but well-founded estimates (e.g. satellite...

    I What purpose does the delta notation serve in this context?

    In a book on atmospheric physics I'm reading, the author begins a derivation by examining a fluid element of volume V = δxδyδz. In this context, what purpose is delta δ serving? Is it just a placeholder for an unspecified volume in the x, y, and z directions, or is it referring to an...

    Guide to Inferring Colors on Alien Worlds: Star Class, Luminosity, Atmosphere

    Is there a guide, based on existing evidence, that I could use to infer realistically how color would be affected on alien worlds due to factors like star class, luminosity, atmospheric composition, etc? I'm planning to develop a not-too-too-distant future scenario where all the stars in...

    Programming languages in atmospheric physics

    I do know this is very vague and maybe a little bit dumb. But are there languages that are ,generally,used much more than others in atmospheric physics?Excluding meteorology. I put this thread in Academic Guidance because this question is translated to "What computer languages should I focus on...

    Can I Reach the End of a Rainbow with a Shovel?

    I'm interested in rainbows. I'm talking about good old fashioned arc/halo rainbows like those you see in the sky. Sometimes you see rainbows from lawn sprinklers. How small would the smallest rainbow arc conceivably possible to view be? Could I make a rainbow at night using a sprinkler with a...
