The Planetary Boundaries framework acknowledges the influence of the 1972 study, The Limits to Growth, that presented a model in which exponential growth in world population, industrialization, pollution, food production, and resources depletion outstrip the ability of technology to increase resources availability.

A convective planetary boundary layer is a type of planetary boundary layer where positive buoyancy flux at the surface creates a thermal instability and thus generates additional or even major turbulence. (This is also known as having CAPE or convective available potential energy; see atmospheric convection.) A convective boundary layer is ...
Vertical profiles of mean variables in convective boundary layer. Adapted from Stull 1988 An Introduction to Boundary Layer Meteorology page 13 (1) The Surface layer is a very shallow region close to the ground (bottom 5–10% of CBL). It is characterized by a superadiabatic lapse rate, moisture decrease with height and strong wind shear. [2]
The atmosphere-terrain boundary interaction follows fluid dynamics, just with processes on hugely varying scales and 'weather' is the planetary boundary layer. The aircraft surface interaction works with the same dynamics, but on a limited range of scales. Forces experienced at any point along a flight path, therefore, are the result of ...

Natalia Anatolievna (Natasha) Artemieva (Russian: Артемьева Наталия Анатольевна, born 1959) is a Russian planetary scientist whose research involves the computer simulation of meteor impacts and the craters formed by them, especially for planets such as the Earth, Mars, and Jupiter where atmospheric effects play a significant role in the impact behavior.
N-body simulation of 400 objects with parameters close to those of Solar System planets. In direct gravitational N-body simulations, the equations of motion of a system of N particles under the influence of their mutual gravitational forces are integrated numerically without any simplifying approximations. These calculations are used in ...
OpenUniverse is a 3D Solar System simulator created by Raúl Alonso Álvarez. It uses OpenGL 1.1 (implemented through Mesa 3D) to simulate the Solar system in complete 3D, including its planets and their major and minor moons, along with a few asteroids with real 3D models created from real data.
