Decadal changes in atmospheric circulation detected in cloud motion vectors.

ABSTRACT: Changing atmospheric circulations shift global weather patterns and their extremes, profoundly affecting human societies and ecosystems. Studies using atmospheric reanalysis and climate model data^1-9 indicate diverse circulation changes in recent decades but show discrepancies in magnitude and even direction, underscoring the urgent need for validation with independent, climate-quality measurements³. Here we show statistically significant changes in tropospheric circulation over the past two decades using satellite-observed, height-resolved cloud motion vectors from the Multi-angle Imaging SpectroRadiometer (MISR)^10,11. Upper tropospheric cloud motion speeds in the mid-latitudes have increased by up to about 4 m s^-1 decade^-1. This acce
