Illustration of the effect of the assimilation of a single observation taken at a middle vertical level of the atmosphere. The gold star marks the location of the observation. The color shades indicate the information provided by the observation about the atmospheric state at the different locations (a and b) at the same vertical level and (c) near the earth’s surface.

(a) Climatological (solid circles) and individual-year (open circles) annual phase-space trajectories of the stratospheric polar vortex (SPV). The color bar indicates the progression through the calendar year. (b) Correlation skill of forecasts for monthly-mean SPV anomalies derived from differences between the predicted and climatological annual phase-space trajectories, shown as a function of…

Observed trend in atmospheric river duration (in hours per year) from 1940 to 2023. Hotspots are the North Pacific and North Atlantic, as well as the Southern Ocean, where an increase will be expected in the future with consequent increase in heavy precipitation.
