North Pacific or Honolulu anticyclone, a region of high atmospheric pressure on perennial charts of averages for all months of the year in the subtropics and tropics of the northern part of the Pacific Ocean, in the area of the Hawaiian Islands. It is one of the centers of atmospheric activity, analogous to the Azores Anticyclone. The name “Hawaiian Anticyclone” reflects the statistical result of the predominance of anticyclones over cyclones in this region. The mean pressure in the center of the Hawaiian Anticyclone in January is over 1.022 × 105 newtons (N)/m2 (1,022 millibars) and in July over 1.026 × 105 N/m2 (1,026 millibars); in summer the Hawaiian Anticyclone extends to higher latitudes. The Hawaiian Anticyclone is associated with the northeast tradewind of the Pacific Ocean, which blows along the periphery on the equator side, and in the summer with the southeast monsoon, which blows in the western part of the Hawaiian Anticyclone from the ocean toward the eastern edge of Asia.
