Why does every tsunami travel differently?

Tsunamis are quite interesting, as they only happen after a large displacement of water. Usually, the waves travel quite weirdly. Sometimes there are waves which bounce off of land and go back to sea....

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 $$ s = (1-q_t)(C_{pd} \ln T - R_d \ln p_d) + q_t C_l \ln T + \frac{q_v L_v}{T} - q_v R_v \ln \mathcal{H} $$ ...

What are the impacts of sublimation on an annual mountain snowpack?

Massive amounts of freshwater rests atop the world's mountains in the form of ice, snow, permafrost, and glaciers. Many areas of the world rely upon the melting of snow and ice to recharge their ...

How can I calculate the average latitudinal temperature anomaly between a city and all other locations along the city's latitude?

E.g. How could I calculate the average temperature anomaly between, say, Boulder, CO and all other locations along the 40N parallel? What about Boulder, CO, and all other locations along 40N at ...

How will cloud feedback effects on the climate change as the result of global warming?

So global warming will increase the tropospheric temperatures, which, in turn, would make the clouds higher than they otherwise would be. And higher clouds (especially cirrus clouds) tend to trap in ...

What are the major differences between weather models and climate models?

Some weather models include GFS (Global Forecast System) and NAM (North American Mesoscale Model). Some climate models include CCSM (Community Climate System Model) and the NASA GISS (Goddard ...

How do weather models work?

We use different weather models all the time, such as the ECMWF and the GFS. These models are simply amazing to me. How do these models work? I know they have to take in various data points - what ...

How do I explain why the Tibetan plateau is colder than lowlands at similar latitudes?

A common layman explanation for why does it get colder to higher elevations (considering only the troposphere here) qualitatively boils down to The Sun heats the Earth's surface and the Earth's ...

How does the pole-to-equator temperature gradient scale with height contours?

Are the pole-to-equator temperature gradients lower at higher heights than at lower heights (like 850 mb/500 mb)? If so, why is it the case? Especially given that the zonal circulation tends to be ...

Why are weather kites no longer used (much) operationally?

Figure 1.12 from the IPCC AR5 WG1 report (reproduced below) illustrates the different instruments that have been used for weather forecasting. Most of the methods have been in continuous use since ...

What determines how fast clouds move?

Do cirrus clouds in the upper troposphere move faster than cumulus and stratus clouds in the lower atmosphere? What about clouds associated with extratropical systems, compared with clouds in the ...

Are there any quantities defined analogically to the virtual temperature, but for other gases?

The virtual temperature is a pseudo-temperature taking into account water vapour in the atmosphere in such a way, that the resulting quantity can be used with the ideal gas law and the molar mass for ...

Have there been any attempts to measure profiles through deep convective systems using dropsondes?

In-situ measurements in deep convective systems, tropical cyclones, etc., are difficult to perform. Few if any people would like to fly a small aircraft close to its core, and radiosondes or larger ...
