The doldrums are also noted for calm periods when the winds disappear altogether, trapping sailing ships for periods of days or weeks. The term appears to have arisen in the eighteenth century, when trans-equator sailing voyages became more common. Since this zone is where two trade
NOx combustion. NO from lightning can become oxidized to produce nitric acid (HNO), this can be precipitated out as acid rain or deposited onto particles in the air. Elevated production of NOfrom lightning depends on the season and geographic location. The occurrence of lightning is more common over land near the equator in the inter-tropical convergence zone (ITCZ) during summer months. This area migrates slightly as seasons change. NO production from lightning can be observed through satellite observations. Scientists Ott et al. estimated that each flash of lightning on average in the several mid-latitude and subtropical thunderstorms studied turned of nitrogen
