“…1. Among them, data from NE and SE are extended to 2000 based on records of warm/cold periods in historical documents (Hao et al, 2011). In TP and NW, some of the original temperature proxies have been updated (in TP: Thompson et al, 2000Thompson et al, , 2003Thompson et al, , 2006Shen et al, 2001;Liu et al, 2006;Wang et al, 2006;Zhu et al, 2008;in NW: Liu et al, 2005;Zhang et al, 2011), and we were able to re-evaluate the records of temperature change in these two regions using the method of Ge et al (2010).…”

We use principal component regression and partial least squares regression to separately reconstruct a composite series of temperature variations in China, and associated uncertainties, at a decadal resolution over the past 2000 yr. The reconstruction is developed using proxy temperature data with relatively high confidence levels from five regions across China, and using a temperature series from observations by the Chinese Meteorological Administration, covering the period from 1871 to 2000. Relative to the 1851–1950 climatology, our two reconstructions show four warm intervals during AD 1–AD 200, AD 551–AD 760, AD 951–AD 1320, and after AD 1921, and four cold intervals during AD 201–AD 350, AD 441–AD 530, AD 781–AD 950, and AD 1321–AD 1920. The temperatures during AD 981–AD 1100 and AD 1201–AD 1270 are comparable to those of the Present Warm Period, but have an uncertainty of ±0.28 °C to ±0.42 °C at the 95% confidence interval. Temperature variations over China are typically in phase with those of the Northern Hemisphere (NH) after 1000, a period which covers the Medieval Climate Anomaly, the Little Ice Age, and the Present Warm Period. In contrast, a warm period in China during AD 541–AD 740 is not obviously seen in the NH

“…Eurasia has suffered from the frequent occurrence of extreme cold events in the past few years (Jeong et al, 2006;Hong and Li, 2009;Zhang et al, 2012). In 2008, long-lasting cold wave events hit central-southern China with disastrous frozen rains and ice storms (Wen et al, 2009;Zhou et al, 2009;Hao et al, 2011). The winter of 2009 was characterized as an extremely cold winter in many cities of China, and also Europe witnessed successive cold outbreaks and record-breaking snow accumulation (Cattiaux et al, 2010;Wang et al, 2010;Lin and Wu, 2012).…”

Distinct impacts of the MJO and the NAO on cold wave amplitude in China

Previous observations suggested a connection between the Madden–Julian Oscillation (MJO) and the North Atlantic Oscillation (NAO), yet few of them contrasted the influences between the MJO and the NAO on extreme weather and climate events. In this study, it is found that the impacts of the MJO and the NAO on winter cold wave amplitude (CWA) over China can be distinctive. Time‐lagged correlation analysis indicates that the response of the CWA to the MJO is characterized by a significant anomalous centre over the Tibetan Plateau and its adjacent region, whereas that to the NAO is mainly over western and northeastern China. The ECMWF model from the Sub‐seasonal to Seasonal (S2S) project can approximately reproduce the relationship between CWA and these indices at intraseasonal time‐scale. The MJO‐associated convective activities along the Equator can modulate the local Hadley circulation. When the convection centre of the MJO is located over the Maritime Continent, it can trigger subsidence over the Tibetan Plateau and its adjacent region, warm the surface and consequently decrease the CWA. When descending flows associated with the MJO prevail over the Maritime Continent due to the eastward propagation of the MJO, the situations tend to be opposite. The intraseasonal variations of the NAO will induce eastward‐propagating Rossby wave trains, which usually favour the significantly positive (negative) pressure, temperature and consequently negative (positive) CWA anomalies over western and northeastern China. Thus, the MJO and the NAO might provide two critical predictability sources for sub‐seasonal forecasts of the extreme temperature events.

“…The authors identify 3 historical cases in 1578, 1620, and 1796−1797, which are very similar in severity and duration to the event in early 2008. With respect to the long-term temperature series (Hao et al 2011, their Fig. 5), the historical ice/snow storm events tended to occur at the end of multi-decadal warm periods, probably signaling a climate shift to a colder regime.…”
