Is increase in atmospheric $\mathrm{CO}_2$ concentration affecting Earth's atmospheric pressure?
It's well known that the $\mathrm{CO}_2$ levels around the world are increasing, leading to an increase in overall surface temperature, etc.
But I'm wondering, are these gases (or the effects from these gases) increasing the global atmospheric…

How can I plot a Skew-T log-P diagram?
For displaying atmospheric soundings the use of Skew-T Log-P diagrams is very common. The manual THE USE OF SKEW T, LOG P DIAGRAM IN ANALYSIS AND FORECASTING from the Air Weather Service explains what this diagram is and how it can be used. What…

Why does it rain more at night than during the day?
I'm living near a sea, and it rains mostly and heavily at night from 11 PM to 3 AM. The weather is mostly clear during daytime.
Air is generally cooler at night, and cool air holds less moisture than warm air resulting in rainfall.
There is a…

Why are impact craters radially symmetric?
Okay, so I believe that most of the impact/collisions happen at oblique angles to the planet's radial direction. (I am not very sure about this, but since it is not a freefall, we can assume that the collision is oblique).
So why are most of the…

Can rocks have pressure signatures?
Since rocks can have magnetic signatures, as is the case with paleomagnetism, can they store past pressures also?
For example, when researchers are trying to determine past ocean levels, they usually look at isotopes. But is there any way they can…

How are low pressure zones tracked across the ocean?
When you look at a surface pressure chart e.g.:
(from http://www.metoffice.gov.uk/public/weather/surface-pressure/#?tab=surfacePressureColour&fcTime=1437480000)
you can see low pressure zones over the North Atlantic ocean. How are these zones…

How do we measure (or empirically calculate) the amount of entropy in the atmosphere and oceans?
Here's a paper on the entropy budget1, where moist entropy is defined in equation (8) as
$$
s = (1-q_t)(C_{pd} \ln T - R_d \ln p_d) + q_t C_l \ln T + \frac{q_v L_v}{T} - q_v R_v \ln \mathcal{H}
$$
In this expression, $q_v$ is the specific humidity…

Optimal vertical coordinate for complex topography
There are plenty of choices in models in so far as choice of vertical coordinate is concerned for meteorological models.
Five that I know of:
The sigma coordinate system - Hybrid coordinate system(used by ECMWF);
Terrain following pressure as…

Discrete Slant Stack on seismic data
In the formula for slant stacking (tau-p transform) a substitution t=tau+d/v is made.
If we consider the substitution as a vector equation then how can vector d/v have the same length as vector t given that in most surveys the number of data points…

What are the benefits of using conservative temperature in oceanography?
The new standard for ocean temperature is the "conservative temperature". It is based on a hypothetical adiabatic and isohaline change in pressure to the sea surface. Conservative temperature was adopted as the standard by the oceanographic…

Did the Neolithic Revolution have an effect on the earth's climate?
I imagine that human agriculture had a major effect on the composition of flora across the planet's surface.
Did the transition from gathering to growing have a measurable effect on climate? If so, what was it?

What are some near term effects of Global Warming?
Many of the predictions of Global Warming models are dated in the range of ~100 years or more from the present. I'm wondering if any models or data provide predictions for the more immediate future, say $10$ - $20$ years from today.
Specifically,…

How can daily brightness be quantified or measured?
It occurred to me that there might very will be a metric out there that measures and quantifies "daily brightness". Meaning, how bright any given day is, taking weather conditions and cloud coverage into account.
A general brightness metric is…

How does the influence of clouds on climate vary with height?
It is generally assumed that clouds affect climate by reflecting sunlight back to space and therefore decreasing the total warming of the Earth. However, stratospheric ice clouds are said to have a net warming effect, due to (I think) the…
