The Model of Generalized Planetary Wind Belts in the Troposphere from the Reference Tables for Earth and Space Sciences (ESSRT) shows the global pattern of winds, pressure belts and convection cells in Earth's lower atmosphere. It primarily supports HS-ESS2-8.

Model of Generalized Planetary Wind Belts in the Troposphere from the Earth and Space Sciences Reference Tables (ESSRT): globe showing the trade winds, westerlies, ITCZ, subtropical highs, jet streams and the Hadley, Ferrel and polar cells by latitude

What the planetary wind belts model shows

The globe is marked with latitude from 90° N to 90° S. Arrows show the prevailing surface winds: the northeast and southeast trade winds, which meet at the Intertropical Convergence Zone (ITCZ) near the equator, and the westerlies in the middle latitudes. Zones of high (H) and low (L) pressure are marked, including the subtropical highs near 30° north and south, along with the Tropics of Cancer and Capricorn and the polar front and subtropical jet streams. Along the edge of the globe, loops show the Hadley, Ferrel and polar cells, with rising and descending air identified in the key. A note states that the patterns shift seasonally.
