Inhomogeneous cloud formation and wavelength-dependent phenomena are expectedto shape hot Jupiter atmospheres. We present a General Circulation Model (GCM)with multiwavelength "picket fence" radiative transfer and radiatively active,temperature dependent clouds, and compare the results to a double gray routine.The double gray method inherently fails to model polychromatic effects in hotJupiter atmospheres, while picket fence captures these non-gray aspects andperforms well compared to fully wavelength-dependent methods. We compare bothmethods with radiatively active clouds and cloud-free models, assessing thelimitations of the double gray method. Although there are broad similarities,the picket fence models have larger day-night side temperature differences,non-isothermal upper atmospheres, and multiwavelength effects in the presenceof radiatively active clouds. We model the well-known hot Jupiters HD 189733 band HD 209458 b. For the hotter HD 209458 b, the picket fence method preventsclouds from thermostating dayside temperatures, resulting in hotter upperatmospheres and the dissipation of dayside clouds. Differences in thetemperature structures are then associated with nuanced differences in thecirculation patterns and clouds. Models of the cooler HD 189733 b have globalcloud coverage, regardless of radiative transfer scheme, whereas there arelarger differences in the models of HD 209458 b, particularly in the extent ofthe partial cloud coverage on its dayside. This results in minor changes to thethermal and reflected light phase curves of HD 189733 b, but more significantdifferences for the picket fence and double gray versions of HD 209458 b.
