Data Supporting "Shutdown of Southern Ocean Convective Centennial Variability under Global Warming and Implications for Climate Projections"

This is the data repository supporting the "Shutdown of Southern Ocean Convective Centennial Variability under Global Warming and Implications for Climate Projections" paper submission. It contains all processed data used to produce figures in the paper. The files are organised by generating model, scenario (as per the IPCC scenario scheme), variant, "R" (folder designation in original system), and then a folder for each variable. The variables are as follows:acc: Antarctic Circumpolar Current strength as calculated across Drake Passage using the barotropic streamfunction (msftbarot).accuo: Antarctic Circumpolar Current strength as calculated across Drake Passage using the uo variable (as described in the paper)avgdensity40s50s: The average ocean density between 40S and 50S using a potential density referenced to the 2000m levelavgdensity50: The average ocean density south of 50S using a potential density referenced to the 2000m levelavgdensity65: The average ocean density south of 65S using a potential density referenced to the 2000m levelavgmlddo: Average mixed layer depth south of 50S, using potential density referenced to a 0m level.lowercircrhon2: The strength of the lower circulation cell, calculated using the mass flux (vmo) on potential density levels referenced to a 2000m level.lowercircrhon2uo: The strength of the lower circulation cell, calculated using the velocity (vo) on potential density levels referenced to a 2000m level.maxmldd0: Maximum mixed layer depth south of 50S, using potential density referenced to a 0m level.siarea: The total sea ice area south of 50S in the Southern Ocean.wwmax: The maximum zonal mean westerly wind strength in the Southern Ocean.本数据集仓库为支撑论文《全球变暖背景下南大洋对流百年尺度变率的抑制及其对气候预估的启示》的投稿工作，包含了论文中所有绘图所用的经处理后的数据。文件按照生成模型、情景（遵循政府间气候变化专门委员会（IPCC）情景框架）、变体、"R"（原始系统中的文件夹标识）进行层级分类，随后为各变量对应的专属子文件夹。 各变量说明如下： acc：基于正压流函数（barotropic streamfunction）计算得到的、跨德雷克海峡（Drake Passage）的南极绕极流（Antarctic Circumpolar Current）强度。 accuo：基于uo变量计算得到的、跨德雷克海峡的南极绕极流强度（详见论文）。 avgdensity40s50s：以2000米为参考面的潜在密度（potential density）计算得到的南纬40°至50°区间内的海洋平均密度。 avgdensity50：以2000米为参考面的潜在密度计算得到的南纬50°以南海域的海洋平均密度。 avgdensity65：以2000米为参考面的潜在密度计算得到的南纬65°以南海域的海洋平均密度。 avgmlddo：以0米为参考面的潜在密度计算得到的南纬50°以南海域的平均混合层深度（mixed layer depth）。 lowercircrhon2：基于以2000米为参考面的潜在密度面上的质量通量（mass flux，vmo）计算得到的下层环流圈强度。 lowercircrhon2uo：基于以2000米为参考面的潜在密度面上的速度（vo）计算得到的下层环流圈强度。 maxmldd0：以0米为参考面的潜在密度计算得到的南纬50°以南海域的最大混合层深度。 siarea：南大洋南纬50°以南海域的总海冰面积。 wwmax：南大洋的最大纬向平均西风强度。
