Paula and Pedro, sailing a round-the-world route from the Mediterranean through the South Atlantic, Indian Ocean, South Pacific, and now northward from Chile toward Alaska, host a webinar with meteorologist Gaby Pérez on North Pacific hurricane risk and the developing El Niño.0:10 Pérez explains the ITCZ (Intertropical Convergence Zone), also called the doldrums, as the convergence of southeast and northeast trade winds near the equator, producing weak variable winds and heavy squalls — conditions Paula and Pedro will cross at roughly 130° West.9:32 He covers the formation requirements for tropical cyclones: sea surface temperatures above 26.5°C to a depth of 50 meters, low wind shear, and sufficient Coriolis force above about 4–5° latitude.18:52 The Eastern and Central Pacific basin is the relevant zone for their route; hurricane season peaks July–August, with 105 recorded storms born in that corridor.18:19 Tropical storm Amanda, active north of their position at the time of the webinar, is cited as a live example.24:13 ENSO (El Niño Southern Oscillation) is explained as a driver of hurricane season intensity in both the Pacific and Atlantic basins, with a developing El Niño warming the Eastern Pacific above climatological norms.35:18 Pérez previews AI and machine learning hurricane track forecasting tools as supplements to standard models like Windy.1:04:28
