Analysis of Twentieth Century Surface Air Temperature Anomalies in China and Globally
This study by Zhou Tianjun and Rucong Yu (2006) investigates the variations in surface air temperature (SAT) anomalies in China, the global average, and the Northern Hemisphere from 1880 to 1999, using coupled climate models. The research includes observed temperature data alongside model simulations from the 20C3M models, providing insights into annual mean anomalies and trends. The paper features detailed figures that illustrate these temperature variations and trends over different periods, enhancing our understanding of climate dynamics both locally and globally.

Zhou Tianjun and Rucong Yu, 2006, Twentieth Century Surface Air Temperature over China and the Globe Simulated by Coupled Climate Models, Journal of Climate, 19(22), 5843-5858.
Figure 1. Observed variations from 1880-1999 of the annual mean China-wide (solid line), global (long dashed line) and Northern Hemispheric (short dashed line) average surface air temperature anomalies in units of ℃.
Figure 2. The (a) global, (b) Northern Hemispheric and (c) Chinese average surface air temperature anomalies simulated by the 20C3M models. Each thin color line corresponds to “run1” of each model.
Figure 3. Same as Fig. 2 except for the ensemble mean of CNRM-CM3, GFDL-CM2.1, GISS_AOM, MRI-CGCM2.3.2 models (long-dashed line), and the single GFDL-CM2.1 model (short-dashed line). The observation is shown as a solid line.
Figure 7. The distribution of the linear trend of annual mean SAT for 1951-1999 in a single realization of the 20CM3 simulation by different models and the observation (Units: ℃/50yr). Negative trends are shaded.
Figure 8. Zonal mean of the (a) JJA and (b) DJF SAT linear trends (1951-1999) over East China (102.5º-122.5ºE) for “run1” of the different models. The observation is shown as thick black line (Units: ℃/50 yr).
