SIZRS- Atmosphere-Ice-Ocean Interactions in the Seasonal Ice Zone of the Beaufort and Chukchi Seas
Abstract
SIZRS is an integrated observation, analysis, and modeling program to better understand and predict the evolution of the Seasonal Ic,e Zone. This proposal is a renewal of the Atmosphere component of SIZRS which focuses on atmosphere-ice-ocean interactions. Atmosphe,ric measurements combined with modeling of the atmosphere-ice-ocean environment yield critical insights into processes that control,the structure of the Arctic atmosphere and its interaction with the ice and ocean. Previously we have examined how well current mod,eling systems represent temperature, humidity, and wind profiles and prescribed pathways to improvement. We assessed the relative ro,les of synoptic and local processes in shaping low level wind and surface ice-edge jets and discovered that clear sky, warm air adve,ction events from Alaska, help determine the onset of sea ice melt in the Beaufort and Chukchi Seas. Over the next 3 years we will b,uild on the existing program and answer these science questions: How do heat and moisture fluxes from open and refrozen leads affect, the boundary layer structure and clouds in the Seasonal Ice Zone. What feedbacks on the sea ice-ocean system arise from this intera,ction? How can we combine in-situ and satellite information to advance our knowledge of these interactions? What impact do observati,ons and advanced representation of processes have on sea ice forecast skill from days to months? To this end we will make measureme,nts from USCG planes that include dropsonde atmospheric profiles, and Laser and IR retrieval of cloud and sea ice properties. This i,nformation will be combined with numerical modeling experiments. USCG flight campaigns will be coordinated with NOAA Arctic Heat and, ICE-PPR.
