Representing icebergs in the iLOVECLIM model (version 1.0) - a sensitivity study

摘要: Abstract. Recent modelling studies have indicated that icebergs play an active role in the climate system as they interact with ocean and atmosphere. The icebergs' impact is due to their slowly released meltwater, which freshens cools consequently alters stratification sea-ice conditions. spatial distribution of meltwater depends on atmospheric oceanic forces acting them well initial size. conducted so far common were moved by reconstructed or modelled forcing fields size was prescribed according present-day observations. To study sensitivity iceberg boundary conditions, we performed 15 experiments using iLOVECLIM model includes actively coupled ice sheet modules, analyse (1) transport, mass melt flux distribution, (2) effect resulting Northern Hemisphere including Greenland sheet, feedback mechanisms such altered temperatures, under different conditions (pre-industrial, high/low radiative forcing). Our results show that, equilibrated pre-industrial currents cause stay close North American coast, whereas quickly distributes further away from calving site. Icebergs remaining last up 2 years longer reside generally cooler waters. Moreover, find local variations sizes do not result states volume, independent prevailing warming cooling climate). Therefore, conclude differences alter continuous supply icebergs. Furthermore, our suggest applied scenarios a stronger than
