Despite a statistically significant increase in wind, linear trends of heat fluxes in the tropical Atlantic are shown to be negative due to a decreased air-water temperature difference and humidity deficit. Significant positive nonlinear trends of total heat fluxes are singled out in the central North Atlantic. Statistical structure of relatively high-frequency fluctuations of hydrometeorological characteristics in the North Atlantic and the role of the ocean and large-scale atmosphere-ocean interaction in the global warming of the lower troposphere are discussed.
