Example diagram of anticyclonic eddies (a–d) and cyclonic eddies (e–h) are combined distribution of atmospheric variables. The atmospheric variables are respectively the wind speed on the sea surface (a,e), the precipitation rate (b,f), the liquid water content in the cloud (c,g), and the water vapor content (d,h). Among them (a1–h1) are the spatial distribution of atmospheric variables around the eddy, the arrow indicates abnormal sea surface geostrophic, “*” indicates the center of the eddy, and the red and blue curve indicates the eddy boundary; (a2–h2) are the variation trend of atmospheric variables with the eddy radius, blue is the atmospheric variables data, red is Fourier fitting data, and Ls is the eddy radius. The above examples are eddy in the northern hemisphere.
