The unpredictability of the weather, either no winds or potential hurricanes, made the Doldrums one of the least favorite sailing lanes back when all that ships had to power them across the ocean was their sails. At which point are the doldrums located? The climate simulations run as part of Coupled Model Intercomparison Project Phase 5 (CMIP5) did not show a consistent global displacement of the ITCZ under anthropogenic climate change. Between about 30 to 35 north and 30 to 35 south of the equator lies the region known as the horse latitudes or the subtropical high. [10] There appears to be a 15 to 25-day cycle in thunderstorm activity along the ITCZ, which is roughly half the wavelength of the MaddenJulian oscillation (MJO).[11].
