The word
"microphysical" refers to things that are very small and related to the physical properties or processes of matter on a tiny scale. It is used to describe the science or study of these extremely tiny particles or phenomena.
Full definition
In addition to advancing our basic understanding of cloud
microphysical processes, the theoretical approach employed in this book supports the explanation and interpretation of laboratory and field measurements in context of instrument capabilities and limitations and motivates the design of future laboratory and field experiments.

cloud microphysical properties is very computationally intensive, so models don't usually include them,» said Fan.

microphysical mechanisms linking these ions to the nucleation and growth of cloud condensation nuclei.
I analyzed the superficial plausibility of Perry's example before in pointing out that it is borrowed from the macroscopic realm which is for all practical purposes deterministic; the predictability of any macroscopic particle is only approximate and does not alter the basic contingencies of the elementary
microphysical events of which a «particle» consists.

But it is possible to assume that ultimately all biological events are determined by laws, mainly by causal laws, in some cases by laws of probability (effective in gene recombination and mutation), the law of conservation of energy and the lawful acting of
microphysical constants.
In the cloud chamber, however, Shaw and Cantrell can control what are called thermodynamic and
microphysical variables - the temperature, pressure, aerosol quantity and water vapor.
However, while the violence in 3 Legged was active to the point of exhaustion, that in Luton is less direct, more subdued,
microphysical rather than spectacular.
«In order to develop climate models, we have to
consider microphysical processes, such as how a cloud droplet gets formed and how such droplets and physical conditions inside and outside of a cloud are changed by the presence of aerosols,» she said.

microphysical structures and hydrometeor phase in convection using radar Doppler spectra at Darwin, Australia.»
Notable changes include the following: the model top is now above the stratopause, the number of vertical layers has increased, a new cloud
microphysical scheme is used, vegetation biophysics now incorporates a sensitivity to humidity, atmospheric turbulence is calculated over the whole column, and new land snow and lake schemes are introduced.
In the context of models that include cloud processes, ranging from small - scale models of clouds and atmospheric chemistry to global weather and climate models, the unified theoretical foundations presented here provide the basis for incorporating cloud
microphysical processes in these models in a manner that represent the process interactions and feedback processes over the relevant range of environmental and parametric conditions.

Measurements from the winter of 1994 — 95 indicating removal of total reactive nitrogen from the Arctic stratosphere by particle sedimentation were used to constrain
a microphysical model.
«Indeed, it is a fascinating aspect of this study that
microphysical processes can have such large - scale, cosmological implications,» Bromm writes.
Most models don't simulate convection well, take into account
the microphysical processes of storm clouds, nor address how pollution interacts with those processes.

Most of the heat entering the ocean arrives via backradiation, as with land, though
the microphysical mechanism is somewhat different.
There are three types of mechanisms that conspire to give a cloud it's id: dynamical (air movements), thermodynamical (temperature / humidity conditions) and
microphysical (droplet collisions, aerosol effects.
Professor William Happer of Princeton, one of the world's foremost physicists, says computer models of climate rely on the assumption of the CO2's direct warming effect that is about a factor two higher, owing to incorrect representation of
the microphysical interactions of CO2 molecules with other infrared photons.
