WHAT IS MCLOUD-1?

MCLOUD-1 ( Mathematical Cloud one-layer network) is a minimal, one-layer
stochastic CA network model of
the Arctic bromine explosion (Arctic BE).

Sketchily, Arctic BE can be characterized by the time-varying total amount BrO and its lifetime. We construct a flow distribution network with a predefined output pattern of the total amount BrO (the satellite BrO samples).

We assume that the predefined output pattern is a distribution made up of the countable number of the mass points < nodes of the abstract network>. From a deeper perspective, the total amount BrO is a distribution over distributions.

We build a minimal network which describes relations of the mass BrO distribution and distribution of the adaptive aerosol loading. Even the minimal solution becomes far from trivial because of the uncertainties in aerosol loads and the lack of data concerning decline phase of Arctic BE.

HOW IT WORKS

SETUP arranges cells in a hexagonal grid, as in Hex Cells Example.
The edges of the grid do not wrap.
Each iterataion network's scatter plot is updated: the SCA network is updated (aerosol loading is updated, set of source nodes is updated (input of the mass BrO) and eligible active cells are updated ( redistribution / propagation of teh mass BrO).

In a scatter plot, active cells are shown in colors according their accumulated nodal mass BrO.

Time series of the total amount BrO and statistics for the network are displayed.

CREDITS AND REFERENCES

The underlying philosophy has been to search for the fundamental principles in atmospehric modeling and ensure that atmospheric research is built on a solid theoretical foundation.
The ultimate progress in earth sciences is impossible without identification of the control factors of the Earth's system. The study of the control factors of the Earth's system is inspired by works of many people, just to name Plato, B. Spinoza, F. Leibnitz, W. Goete, J. von Neumann,
J. Lovelock, L. Margulis, B. Mandelbrot, S. Wolfram. Offered stochastic network simulates statitical distributions of the physisicochemical atmospehric boundary layer.
The atmospehric science research and relevant <stochastic cellular automata> mathematical conceptualization are not yet combined together, only some annotations exist.
The NetLogo computing environment and software of U. Wilensky have well suited needs for the embodiment of the key points and ideas.
