Fig. 3From: Seasonal modulation of the Asian summer monsoon between the Medieval Warm Period and Little Ice Age: a multi model studySimilar to a Fig. 2a and b Fig. 2b, but for tropospheric thickness (m) between the 200 and 500 hPa levels. Vectors indicate vertical wind shear (m s−1) between 850 and 200 hPa levelsBack to article page
