Book Description
A case study of the Andreas et al. (1984) data on atmospheric boundary layer modification in the marginal ice zone is made. Our model is a two-dimensional, multi-level, linear model with turbulence, lateral and vertical advection, and radiation. Good agreement between observed and modeled temperature cross-sections is obtained. In contrast to the hypothesis of Andreas et al., we find the air flow is stable to secondary circulations. Cloud top longwave cooling, not an air-to-surface heat flux, dominates the cooling of the boundary layer. The accumulation with fetch over the ice of changes in the surface wind field are shown to have a large effect on estimates of the surface wind stress. We speculate that the Andreas et al. estimates of the drag coefficient over the compact sea ice are too high. Keywords: Atmospheric boundary layers; and Air-sea-ice interaction.

Book Description
Ice drift in the marginal ice zone (MIZ) is a very important feature of air-ice-ocean interaction at high latitude. Thermally generated surface winds, blowing from ice to water (ice breeze) with some deflection due to the earth rotation, force the ice drift and ocean currents near the MIZ. By changing the surface temperature gradient, the ice motion and the ocean currents feed back on the surface winds. A coupled air-ice-ocean theoretical model for the MIZ is employed to discuss the ice drift pattern with such a feedback mechanism. The steady-state solutions show that an off-ice and divergent wind field not only producee a dilation of the MIZ (as people generally think), but also generates a compaction of MIZ for some circumstances. An ice divergence/convergence criterion is found. The time-dependent solutions show that the ice motion exhibits two bifurcations. First, it bifurcates into decaying and growing modes. Second, the growing mode bifurcatee into non-oscillatory and oscillatory states. Finally, the model predicts the ice edge upwelling.

Book Description
Extreme weather and climate change aggravate the frequency and magnitude of disasters. Facing atypical and more severe events, existing early warning and response systems become inadequate both in scale and scope. Earth Observation (EO) provides today information at global, regional and even basin scales related to agrometeorological hazards. This book focuses on drought, flood, frost, landslides, and storms/cyclones and covers different applications of EO data used from prediction to mapping damages as well as recovery for each category. It explains the added value of EO technology in comparison with conventional techniques applied today through many case studies.
