«Prior analyses have found that climate models underestimate the observed rate of tropical widening, leading to questions on
possible model deficiencies, possible errors in the observations, and lack of confidence in future projections,» said Robert J. Allen, an assistant professor of climatology in UC Riverside's Department of Earth Sciences, who led the study.
There are bound to be uncertainties and poor parameterizations in them; however, as time goes on, we are ironing out those
deficiencies intrinsic to the
model or developing the understanding necessary to cut them out as smoothly as
possible.
