<P> Tropical regions (between the Tropic of Cancer and the Equator) are generally hot all year round and tend to experience a rainy season during the summer months, and a dry season during the winter months . </P> <P> In the Northern Hemisphere, objects moving across or above the surface of the Earth tend to turn to the right because of the coriolis effect . As a result, large - scale horizontal flows of air or water tend to form clockwise - turning gyres . These are best seen in ocean circulation patterns in the North Atlantic and North Pacific oceans . </P> <P> For the same reason, flows of air down toward the northern surface of the Earth tend to spread across the surface in a clockwise pattern . Thus, clockwise air circulation is characteristic of high pressure weather cells in the Northern Hemisphere . Conversely, air rising from the northern surface of the Earth (creating a region of low pressure) tends to draw air toward it in a counterclockwise pattern . Hurricanes and tropical storms (massive low - pressure systems) spin counter-clockwise in the Northern Hemisphere . </P> <P> The shadow of a sundial moves clockwise in the Northern Hemisphere (opposite of the Southern Hemisphere). During the day, the Sun tends to rise to its maximum at a southerly position except between the Tropic of Cancer and the Equator, where the sun can be seen to the north, directly overhead, or to the south at noon dependent on the time of year . </P>

How many latitudes are there in the northern hemisphere
