Sin. A study of the role of the Tibetan Plateau's thermal forcing in modulating rainband and moisture transport in eastern China (in Chinese). J. Atmos. In addition, ENSO was significantly modulated by the PDO, which furtherly affected on the SCSSMP (Lee et al., 2013; Feng et al., 2014; Song and Zhou, 2015; Bollasina Massimo and Gabriele, 2018). The trend is therefore reliable and robust, despite the annual variability after 2005. Observations used are mainly from the China Meteorological Science Data Network. 121:476. doi: 10.1002/2015JD023476, Lawrimore, J., Menne, M., Gleason, B., Williams, C., Wuertz, D., Vose, R., et al. P < 0.01 indicates a significant difference above the 99% confidence level. (2017) chose the grids above 2,000 m from the reanalysis datasets to quantitatively analyze the warming amplification over the Tibetan Plateau. Red dashed lines represent wave-like structures. More chances to get the soft-sleeper Tibet train tickets if you book early with us. Red dashed lines represent wave–like structures. 2, 100-116. doi: 10.1093/nsr/nwu045. We add the variables of PDO, ENSO, and AMO by one after another. The weakening relationship between Eurasian spring snow cover and Indian summer monsoon rainfall. Figure 9. The similarity precipitation distribution patterns between these two datasets confirm that the GPCP precipitation data well reflects the precipitation in China and even in East Asia. The only suggestion is that it is hard to get a Tibet train ticket in summer holiday, especially from July to August, and from late September to early October, when it is the peak season for domestic tourists traveling to Tibet. The wind structure and heat balance in the lower troposphere over Tibetan Plateau and its surrounding, Acta Meteorol. Zhao, S. R., Song, Z. S., and Ji, L. R. (2003). However, the temperature difference between day and night can be drastic. The climate in southeastern Tibet (e.g. Dyn. Yanai, M., Li, C. F., and Song, Z. S. (1992). Hollow rhombuses indicate significant differences above the 90% confidence level based on the Student's t–test. IEEE Trans. The wet season at EBC is from June to September, and is influenced by the Indian monsoon, bringing frequent rainfall and many cloudy days. (1992). The Tibetan Plateau (TP) plays a critical role in influencing regional and global climate, via both thermal and dynamical mechanisms. Is it too cold to visit Tibet in winter? Appl. The interdecadal variation of the TPST significantly affect the hemispheric atmospheric circulation, furtherly leading to the change of the SCSSMP. 8:583466. doi: 10.3389/fenvs.2020.583466. J. Geophys. Effects of the Qinghai-Xizang(Tibetan) Plateau on the circulation features over the plateau and its surrounding areas. The PDO index is downloaded from the National Centers for Environmental Information (NCEI) by using the NOAA's Extended Reconstruction of Sea Surface Temperature (ERSST Version 4). But rest assured, you can visit any time you like. Revisiting swiss temperature trends 1959-2008. Increasing temperature. The 2–m global surface temperature from JRA55 is also analyzed to compare this trend with that of global warming. Climatic change in mountain regions: a review of possible impacts. Heating Effect of the Tibetan Plateau on rainfall anomalies over North China during rainy season (in Chinese). In the later period, a wave–like structure in the low–latitude moves easterly along the low–level monsoon and a strong cyclonic circulation exists in the South China Sea, which is consistent with the negative correlation between the TPST–OLR. Combining the divergence at 200 hPa and convergence at 700 hPa over the South China Sea, strong convection is more likely to occurs and lead to water vapor converge, which means the likelihood of rain increase in the later period. 39, 1169-1181. doi: 10.1007/s00382-012-1334-z, Wu, G. X., Liu, Y. M., He, B., Bao, Q., Duan, A. M., and Jin, F. F. (2012a). 67, 181-198. doi: 10.1007/BF01277509, Zhang, T., Wang, T., and Krinner, G. (2019). 51, 3537-3557. doi: 10.1007/s00382-018-4095-5, Boos, W. R., and Kuang, Z. M. (2013). Res. Shading indicates significant differences above the 90% confidence level based on the Student's t–test. The annual average temperature is 2 ℃, the average temperature of the warmest month is 10-18 ℃, the average temperature of the coldest month is - 10 ℃ Meanwhile, as the largest high-elevation part of the cryosphere outside the polar regions, with vast areas of mountain glaciers, permafrost and seasonally frozen ground, the TP is characterized as an area sensitive to global climate change. Atmos. Combining all datasets, the time series is separated into two periods, 1980–1994 and 1998–2016. From November to March, which is the dry season, there is very little rain, and the area sees the most sunshine for the year. In addition to TPST, global warming, interannual, and interdecadal variability, such as WNPSH, ENSO, PDO, and AMO, can also influence the summer rainfall in this area. (1991). Bollasina Massimo, A., and Gabriele, M. (2018). The following are the monthly temperature and weather condition of the major destinations in Tibet. However, the nighttime drop in temperature is equally as large, with temperatures dropping to as low as minus 7 degrees in December and January. Bull. Monsoons are caused by the different amplitudes of surface temperature seasonal cycles between land and oceans. In section 3, the constructed stepwise regression model and the changing relationship of TPST–SCSSMP are documented. Decadal change in the correlation pattern between the Tibetan Plateau winter snow and the East Asian summer precipitation during 1979-2011. Sci. Red line represents the forward line; Green line represents the back line. 10, 288–296. Received: 15 July 2020; Accepted: 26 October 2020; Published: 26 November 2020. 4:1147–1167. The Outgoing Longwave Radiation (OLR) dataset is also used. (2003). Change. Why April to May and September to October are the Best Seasons to Visit Everest Base Camp. You can just pick up your favorite itinerary and choose the date you like. The Mann–Kendall (M–K) trend test and Theil–Sen estimator are both used to check the reliability of trend. In addition, the cloud–radiation effects on water vapor and radiative fluxes (Rangwala, 2013), are also responsible too. Ocean heating is distributed vertically through a "mixed layer" that may be 50 meters deep through the action of wind and buoyancy-generated turbulence, whereas the land surface conducts heat slowly, with the seasonal signal penetrating only a meter or so. 134, 1287-1299. doi: 10.1007/s00704-017-2341-0, Xu, X. D., Lu, C. G., and Shi, X. H. (2010). Nagqu), the average temperature is below zero degrees; while in Lhasa and the central part of Tibet, the climate is normal and nice for traveling. Guarenteed hard-sleeper train ticket to Tibet. The peak season for Tibet tourism is normally from April to October, while the low season runs from November to January, with a closure of the region to foreign tourists during February and March. Climate - Tibet Average weather, temperature, rainfall, when to go, what to pack Redirect note. It is also supported by the project of Enhancing School with Innovation of Guangdong Ocean University (230419053); Projects (Platforms) for Construction of Top-ranking Disciplines of Guangdong Ocean University (231419022); Special Funds of Central Finance Support the Development of Local Colleges and Universities (000041). Ye, D. Z., and Gao, Y. X. Further discussions are still needed. These results suggest that the summer diabatic heating over TP is likely enhance after 1998. (1957). Applied Regression Analysis. Large-scale topography of China: a factor for the seasonal progression of the Meiyu rainband? Int. Tibetan Plateau serves as a water tower. In the Tibetan capital, it rises above freezing in time for the Tibetan New Year celebrations. Autumn is also a prime time to visit, as the leaves are turning brown and the weather is warm and clear. doi: 10.1029/2008GL034330, Wang, Q., Fan, X., and Wang, M. (2014). Res. Hahn and Manabe (1975) suggested that the interannual variation of the TP heating likely modulated a Meiyu rain belt. J. Why spring and autumn are the best seasons to visit Everest Base Camp? According to the thermal adaptation, the TP heating will result in a shallow cyclonic circulation at low-level and a deep anticyclonic circulation at high-level, which is consistent with the significant anticyclonic anomaly at 200 hPa (Figure 8). Environ. The Mann–Kendall and Theil–Sen estimator are both used to check whether the trend is robust. Figure 5. Recently, He et al. Trends in summer rainfall over China associated with the Tibetan Plateau sensible heat source during 1980-2008. Then we only analyze the standardized partial regression coefficients between the TPST and precipitation, as well as evaluating the relative contributions to precipitation. For the download websites and resolutions of all above datasets, please see Table 1 for detail. Clim. 28, 7093-7107. doi: 10.1175/JCLI-D-14-00783.1, Stanley, S. (2017). Figure 7. (2002). ENSO together with the AMO caused the WNPSH anomalous cyclone (anticyclone), strengthening (weakening) the SCSSMP (Wu et al., 2003; Fan et al., 2018). Thermal adaptation, overshooting, dispersion, and subtropical high. The purple area (27–40°N, 90–105°E) is selected as the research region for JRA55, ERA5 and ERA-Interim reanalysis temperature data at 2 m. To test the reliability of the reanalysis data in reflecting the TPST change, we compare it with the station data at the same region (eastern Tibetan Plateau; purple box in Figure 1). All of them are statistically significant at the 95% confidence level. The stepwise regression is a widely–used method for fitting regression models.
