| Country | Climate |
| Northern Mariana Islands | tropical marine; moderated by northeast trade winds, little seasonal temperature variation; dry season December to June, rainy season July to October |
| Norway | temperate along coast, modified by North Atlantic Current; colder interior with increased precipitation and colder summers; rainy year-round on west coast |
| Oman | dry desert; hot, humid along coast; hot, dry interior; strong southwest summer monsoon (May to September) in far south |
| Pacific Ocean | planetary air pressure systems and resultant wind patterns exhibit remarkable uniformity in the south and east; trade winds and westerly winds are well-developed patterns, modified by seasonal fluctuations; tropical cyclones (hurricanes) may form south of Mexico from June to October and affect Mexico and Central America; continental influences cause climatic uniformity to be much less pronounced in the eastern and western regions at the same latitude in the North Pacific Ocean; the western Pacific is monsoonal - a rainy season occurs during the summer months, when moisture-laden winds blow from the ocean over the land, and a dry season during the winter months, when dry winds blow from the Asian landmass back to the ocean; tropical cyclones (typhoons) may strike southeast and east Asia from May to December |
