This model describes three types of forces: electromagnetic interactions, which cause all phenomena associated with electric and magnetic fields and the spectrum of electromagnetic radiation; strong interactions, which bind atomic nuclei; and the weak nuclear force, which governs beta decay — a form of natural radioactivity — and hydrogen fusion, the source of the sun's energy.
In 2010, model simulations of rocky super-Earths between two and 10 Earth - masses indicated that high pressures could keep their cores solid instead of molten, which would prevent a protective magnetic field from forming protecting developing surface life from stellar radiation.
I used to be active in the radiation field, indeed I co chaired the first ICRCCM study (Intercomparison of Radiation Codes for Climate Models).
Based on measurements of ecosystem CO2 flux, radiation absorption by plants, crop yields and a model simulating the terrestrial biosphere, a multinational team of researchers has found that during July and August 2003, 500 million tonnes of carbon escaped from the forests and fields across Europe as a result of extreme heat and drought.
3) In the examination of the model for the GHE above, the initial radiation balance, plus the adiabatic - lapse rate, is what has set the structure of the temperature profile; and then the addition of more GHG to the temperature field causes a radiative imbalance that changes the temperature profile until the imbalance goes away.
Models participating in the cloud - forcing MIP (CF - MIP) should already have the capability to separately call their radiation code with their GCM's cloud field and with clouds removed.
Keep in mind that when using reanalysis data, the radiation parameters are strongly dependent on * modeled * cloud fields.
