Atmospheric physics Definition and 16 Threads

When displaying atmospheric pressure, weather apps show absolute pressure. I understand that it is the definition, but usually the atmosphere is at 1 atm ##\pm## corrections of the order of 1% or 0.1%. Such changes are what matters. Would it not be better to use differential pressure put 1 atm...

Hello: Heard in the news that there is massive fire disaster in los angeles , california And a question came to me , what about cloud seeding isn't it a possible method to help handling this disaster How much time will take from cloud seeding start date until it start to rain on the fire...

I love weather and atmospheric physics! So when I recently read Dune, I couldn’t stop thinking about the “Coriolis Storm”, wondering if such a crazy storm could really exist, ripping around an Earth-like planet at 700 km/h. For me, this became a worldbuilding exercise: What makes the windiest...

That question has been puzzling me recently. But I know there is a simple answer to it.

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...

Hello everyone! I'm currently an Aerospace major student entering my third year of college, studying in northern Mexico. After enrolling in a summer school by Mexico's national space weather lab, I have been offered an opportunity to participate in the development of an ionosonde antenna in my...

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...

Homework Statement For an atmospheric physics class, we are given this problem that I and a classmate have been struggling with for days. Reaching out here for some help. Full Problem statement in the image attached. We have a balloon at 293 K and 101,300 Pa. How much fuel is needed to raise...

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...

Can you suggest possible master thesis topics relating to atmospheric physics? I have a bachelor's degree in physics and I mostly comfortable in numerical and theoretical physics. Since this field is somewhat new to me, I need to have a number of options on what topics to choose from. Thank you...

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...

Homework Statement Suppose ##10^{14} kg## of carbon dioxide was released into the atmosphere and absorbed completely, what is the percentage change of carbon dioxide concentration? Take initial atmospheric mass mixing ratio to be ## 5.7 \times 10^{-4} kg/kg##. Homework EquationsThe Attempt at...

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...

Homework Statement Is there any way we can measure the thickness of an exposed PTFE membrane air sampling filter? An unexposed filter (from the filter datasheet) has a thickness of 40μm. We have 5 ambient air exposed filters with the following mass concentrations: 1μg/m3 (filter 1), 20.1 μg/m3...

I'm a 2nd year applied physics student in university and I'm wondering if anyone has advice on careers in atmospheric physics / geophysics. Although it is controversial I would like to go into the field of research of climate control by injecting volcanic ash into the atmosphere. Does...

Homework Statement Consider a layer of unsaturated air on Earth, 2000 m thick, whose base is at a height of 4000 m above sea level. The layer sinks and is compressed till its base is at 350 m and its top is at 1650 m. If the layer now provides a subsidence inversion, calculate the maximum...
