The horizontal and vertical profiles of the atmospheric circulation responses to the tropical SST forcing in the atmospheric model experiments. a Shows the horizonal profile of the surface wind response (vectors) to the SST forcing in the pan-tropical-forcing experiment, with the contours illustrating the 200 hPa geopotential height. c Shows the vertical profile of the same experiment, with vectors representing the zonal and vertical velocity, and the color shading illustrating the intensity of the vertical pressure velocity (omega, red indicates negative values and represents upwelling motion). b, d Show the horizontal and vertical profiles of the circulation responses in the Atlantic-forcing experiments. e, g Show the horizontal and vertical profiles of the circulation responses in the Pacific-forcing experiments, and f, h show the horizontal and vertical profiles of the circulation responses in the Indian Ocean-forcing experiments
