How do the oceans affect the weather in Colorado?
The Earth has one big ocean that is interconnected. The temperature, salinity, and density of ocean water and global winds and air temperatures are caused by the Sun and geologic processes. These factors cause the ocean water to circulate with basins and between the water and atmosphere.

Lecture Abstract: This presentation will explore the physical processes believed to be producing the observed drastic reduction in Arctic sea ice, emphasizing the interactions between sea ice and atmospheric processes. A key metric for the interaction with sea ice is the surface energy fluxes, and the primary atmospheric processes modulating surface energy fluxes include cloud radiative effects, atmospheric turbulent effects, and their linkages to storms. Direct radiative effects by greenhouse gases along with oceanographic and cryospheric mechanisms will also be discussed briefly. Field programs focused on understanding these processes demonstrate how the science is being advanced and the logistical difficulties involved. The explanations for the change in Arctic sea ice incorporate the basic radiative and global circulation concepts discussed in the first lecture by Dr. Fairall.
