TEA scientists and staff

Major progresses were made in development of regional environmental model system (RIEMS), interactions among land use, ecosystems, and monsoon climate, mechanisms and impacts of extreme climate events such as mega-drought, and effects of urbanization on climate. TEA currently has 42 employees, including 2 academicians and 12 senior professors in multiple disciplines such as atmospheric physics, atmospheric chemistry, geosciences, and ecology, along with over 30 graduate students.

Climate change is highly heterogeneous over the globe, with strong regionality. Scientific community need to better understand the timing and magnitude of regional climate change, and environmental and socio-economic consequences of the changes. Climate in East Asia is characterized with seasonal shifting of prevailing wind and fluctuation of precipitation and temperature. Monsoon system has major impacts on life and economy in the region; meanwhile, intensified human activities and rapid economic development will likely cause feedbacks to regional climate through modifying land surface and atmospheric chemistry. Meeting those science challenges requires understanding of the physical science basis of climate change, consideration of its impacts on all spheres of human activity, and development of policy strategies and actions.

Established in 1978, the CAS Key Lab of Regional Climate-Environment for East Asia (TEA) is dedicated to enhance scientific understanding on the ever changing climate and environment, to build the capability of predicting changes in global-regional linkages in the Earth System and risks of such changes, and to provide sound scientific basis for sustainable development in the region through the use of field experiments, satellite remote sensing, modeling, and synthesis. TEA strives to serve society by directing its observation and synthesis to decision making and public awareness related to emerging issues of climate impacts, extreme events and natural disasters, and related environmental problems.

TEA is also the START Regional Center for East Asia.

Introduction

Regional integrated environmental model system (RIEMS)

From Earth system point of view, the East Asia monsoon system may not be considered as a purely physical system; instead, it is a coupled physical/ biological/ chemical/ social system. Recognized the regionality of East Asia monsoon climate, a regional integrated environmental model system (RIEMS) was developed by TEA. RIEMS was built on the thermodynamic frame of PSU/NCAR MM5, into which a land surface scheme BATS1e and radiative transfer scheme- the revised CCM3 are integrated. RIEMS considers both large scale forcing and regional anthropogenic forcing. The latest version RIEMS is further featured with regional ocean, dynamic vegetation, hydrology, and atmospheric chemistry modules.

AVIM is a fully coupled biosphere-atmosphere processes model developed by TEA scientists. It consists of two interactive modules: PHY, a land surface physical process module; VEG, a vegetation eco-physiological process module, which includes photosynthesis, respiration, allocation, litter fall, and phenology processes. It is used to simulate responses and feedbacks of vegetation to regional climate dynamics.

The Tongyu Field StationThe Tongyu Field Station is a long-term land-atmosphere observation and research facility operated by TEA. It was established in 2002, and consists of a grassland site and cropland site to represent dominant land surface in semi-arid northern China. It was designed to conduct long-term observation on the human activities, land-atmosphere exchange, and ecological

by working closely with 25 field research stations operated by various research institutes and universities over the region. It is a science driven, volunteer, and mutual benefit network that bring those stations together with common observation

protocols, instruments calibration, and data quality control to ensure data compatibility. Post calibrated data from all participant stations are shared within the network, along with field-satellite integrated spatial dataset. Training on observation and data analysis are also regularly organized in the project.

Regional Modeling Inter-comparison Project - RMIP Asia

Monsoon Asian Integrated Regional Study (MAIRS)

RMIP is supported by the Asia-Pacific Network for Global Change Research (APN) and dedicated to development of regional climate and environment models through inter-comparisons, and their applications for East Asia. The objectives of the project are: 1) to assess the status of East Asian regional climate simulations; 2) to provide more solid knowledge for further improvement of RCM applied for east Asia; and 3) to improve the confidence level for using RCM’s simulated results. It has been carried out in three phases since 2000, with 12 participant regional models from Australia, China, Japan, Korea, and USA. In current third phase, RMIP focuses on multi model ensemble in regional climate simulation and climate change projection.

START Regional Center for East Asia is one of five regional research centers under the Global Change System for Analysis, Research & Training (START).

START, founded in 1992, promotes research-driven capacity building to advance knowledge generation and sharing on global environmental change issues. Its work is carried out by regionally based centers in Africa and Asia-Pacific, together with the International START Secretariat based in Washington, DC. On an annual basis, START engages over 1,000 scientists, policymakers, and practitioners from developing countries in its research, training and outreach programs.

with projects for each of the four scientific themes: coastal areas, highlands, dry lands, and urban areas. The vision of MAIRS is to significantly advance our understanding of the interactions between the human-natural components of the overall environment in the monsoon Asian region and implications for the global earth system, in order to support the strategies for sustainable development.
