Modelling the solar irradiance during the Maunder Minimum and the corresponding cooling
- UNAM, Mexico City (Mexico)
Expressions to compute the solar irradiance as a function of the sun rotation rate, sunspot number and solar cycle length, are deduced. They yield a solar irradiance dimmed by about 0.5% during the Maunder Minimum (1660-1720). This parameter is put in the Adem thermodynamic model as an external forcing to simulate the corresponding climate change. Another forcing used is the preindustrial level of atmospheric CO{sub 2} which reinforces the cooling. The model generates three internal feedbacks: cryosphere, cloudiness and water vapor. The output is a cooling of about 0.5 to 1 C, with respect to present climate, depending on the forcings and feedbacks included. These results agree well with those from other authors and with the few historical records.
