Satellite Based Downward Long Wave Radiation by Various Models in Northeast Asia

Evaluation of satellite and reanalysis products of downward surface solar radiation over East Asia: Spatial and seasonal variations

[1] Surface solar radiation plays a crucial role in surface energy and water budgets, and it is also an important forcing for land hydrological models. In this study, the downward surface solar radiation (DSSR) from two satellite products, the Fengyun-2C satellite (FY-2C) and the Fast Longwave and Shortwave Radiative Fluxes project (FLASHFlux), and two reanalysis datasets, NCEP-DOE and ERA-Inte...

Geopolitical Issues of Natural Gas Trade in Northeast Asia

 This work was supported by the Academy of Korean Studies of the Republic of Korea in year 2012-2013 (AKS-2010-CAA-2101) Energy security has assumed newfound geopolitical importance at the outset of XXI century (Moran and Russell, 2008). Diminishing fossil fuel supplies have led to fears of energy shortages, while rapid economic and population growth have fuelled the demand for cheap, clean and...

Northeast Asia Ripe for Integration

Prospects for Economic Cooperation in Northeast Asia

In contrast to developments in other world regions, efforts to institutionalize regional economic cooperation in East Asia have been weak. Though Southeast Asian economies have taken action toward trade liberalization (ASEAN Free Trade Area), the major economies of the region such as China, Japan and Korea have not been part of any formal trade groupings until recently. Ongoing economic coopera...

Downward Wave Propagation on the Polar Vortex

This paper considers the propagation of waves on the edge of a stratospheric polar vortex, represented by a three-dimensional patch of uniform potential vorticity in a compressible quasigeostrophic system. Waves are initialized by perturbing the vortex from axisymmetry in the center of the vortex, and their subsequent upward and downward propagation is measured in terms of a nonlinear, pseudomo...
