Chapter 5 Atlantic Periphery

     The Atlantic Periphery does not apply to Honolulu.  The Atlantic Periphery includes the Canadian provinces of Newfoundland and Labrador, Nova Scotia, Prince Edward Island, and New Brunswick.  These four provinces are known as the Atlantic Periphery.  (Hadwick, pg. 91) I will be covering the Honolulu's climate.

     Mild temperatures, cool and persistent northeasterly winds, a rainy season from October through April, and a dry season from May through September characterize the climate of Oahu (Blumenstock and Price, 1967; Sanderson, 1993). Topography and the location of the north Pacific anticyclone relative to the island primarily control the climate of Oahu. During the dry season the stability of the north Pacific anticyclone produces persistent northeasterly winds, known locally as trade winds, that blow 80 to 95 percent of the time. During the rainy season, migratory weather systems often move past the Hawaiian islands, resulting in less persistent trade winds that blow 50 to 80 percent of the time. Southerly winds associated with low-pressure systems can bring heavy rains to the island. The dry coastal leeward areas receive much of their rainfall because of these low-pressure systems. During heavy storms, 24-hour rainfall can exceed 10 in. over coastal areas and 20 in. over the mountainous interior of the Koolau Range (Giambelluca and others, 1984).
