Current data are provided by the CORA dataset.
In addition to answers to the main question, there are a few more points I'd like to know:
How can one forecast ocean…

Intuitive definition of the Monin-Obukhov length?
The Monin-Obukhov length (L) is defined as:
$$L = - \frac{\rho C_p T_v u^3_*}{kgH}$$
where $\rho$=moist air density; $C_p$=air specific heat capacity; $T_v$=virtual temperature; $u^3_*$=wind friction velocity; $k$=0.41 (von Karman constant);…

Do forests affect local rainfall and climate significantly?
I know that forests can change the local temperature, but what about rainfall?. Do forests affect rainfall in their region? I have read that if a forest is very big, it can cause minor changes to local rainfall and temperature. How does that work?

Climate on an Earth without an Axial Tilt
The Premise
The Earth rotates on its own axis, which is tilted by about 23 degrees. I am imagining a situation where such an axial tilt does not exist.
From general reading, it appears the largest impact of removing an axial tilt would be on…
