In this paper,based on the original meteorological data,the winter ventilation design temperature in Code for Design of Heating Ventilation and Air Conditioning(GBJ 19-87) was firstly discussed.

The article reviewed the history of outdoor design temperature for heating.

Recently,many studies have described the relationship between winter temperature in China and some climate systems including the Siberian high(SH),the Arctic Oscillation(AO),ENSO and the western Pacific teleconnection pattern(WP).

warmer,normal and colder categories)is proposed based on the winter temperature data observed at 565 stations in China during 1956-2005,where the IWWI is defined as the ratio of the station number of warmer category over the total number of stations.

The value of outdoor computational temperature during heating period influences correctness of design load for heating,and that influences thermal comfort of heating system,energy consumption and building investment.

1 and the distributions of heat source calculated by NCEP/NCAR(version 1) reanalysis datasets,the impact of atmospheric cold(heat) source distribution over Asia and the Southern Hemisphere in January on East Asian winter monsoon and Indian winter monsoon are investigated.

The impact of atmospheric cold(heat) source distribution over Asia and the Southern Hemisphere in January on the East Asian winter monsoon and Indian winter monsoon is simulated with the NCAR CAM3.
