TYPHOONS     Do you ever wonder when typhoons occur or how they travel? Well then, read on.  The dangerous tropical storms that sweep on top of the Pacific Ocean from the Philippine Islands to Japan and the coast of China are called typhoons. Storms that are like typhoons are called hurricanes. Typhoons occur the most from July to October.Typhoons start in low latitudes in the North Pacific, move northwest, and then turn northeast. These storms do a lot of damage in Japan. The western Pacific typhoons cut a storm path 50 to 100 miles (80 to 160 kilometers) wide. They travel slowly, but these violent gusty winds within the circle of the typhoon cause great destruction.  Each year, up to 25 typhoons occur in the Northern Pacific Ocean, which is above the equator. Like hurricanes, typhoons travel westward.
