Modeling Human Dispersal
The genus homo started about 3-2.5 million years ago – likely in the savannas of Eastern Africa. Over the following 2 million years further speciation events occurred and some groups, […]

History of the Development of Numerical Models of the Ocean
In the early 1950’s John von Neumann and Jules Charney carried out the first successful numerical weather forecasts at the Institute of Advanced Study at Princeton. The United States Weather […]
Precipitation Patterns in Korea through the Geostatistical Analysis and the Principal Component Analysis
Most precipitation systems in Korea are highly influenced by the East Asian summer monsoon (Changma) as well as by synoptic scale/mesoscale weather phenomena, and hence have high seasonal variation; they […]
Reducing Uncertainties in Land Surface Modeling through Parameterization Scheme Development and Optimal Parameter Estimation
Land surface is the interface between atmosphere and land, which is composed of various soils, vegetations, surface water bodies, snow/ice etc.; thus, it represents various components of the Earth’s environment/climate […]
Improving Regional Climate/Weather/Environment Prediction: Coupled Modeling, Parameter Optimization and Data Assimilation
Numerical prediction of climate/weather/environment is an important tool for adequate policy making in an era of changing climate. It basically requires a coupled modeling system, and its performance can be […]
Cold-season Arctic amplification driven by Arctic Ocean-mediated seasonal energy transfer
During recent decades, the Arctic has been warming at a much faster rate than the global average. Interestingly, this accelerated warming in response to greenhouse gas forcing is most pronounced […]
Volcanic eruption, global monsoon, and El Niño
Tropical volcanic eruptions are known to induce a decrease in global monsoon precipitation but there remains a large uncertainty in model simulated responses. Here we show that the inter-simulation differences […]
Modern vs past abrupt changes in the Arctic
The Arctic is currently warming at a high rate of change, with an average amplitude twice the global mean. Are these changes unprecedented in the climate record as we know it? […]
How large-scale atmospheric circulation changes drive fire activity in Equatorial Asia and southeastern Siberia?
Fire activity in Equatorial Asia shows large interannual variability. Teleconnections by El Niño‐Southern Oscillation and Indian Ocean Dipole are linked to drought and fire events; however, we found here that […]
Role of Maritime Continent Land Convection on the Mean State and MJO Propagation
The Maritime Continent (MC) region is known as a ‘barrier’ in the life-cycle of the Madden-Julian oscillation (MJO). During boreal winter, the MJO detours the equatorial MC land region southward […]
