1998 Pacific Typhoon Season
The 1998 Pacific typhoon season was at the time the least active Pacific typhoon season on record, until the record was surpassed 12 years later, spawning 16 tropical storms and 8 typhoons. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1998 Pacific hurricane season. Tropical Storms formed in the entire west Pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names. The 1998 season was very weak compared to the 1997 season; this was due to the strong El Niño in the previous ...

Typhoon Zeb (1998)
Typhoon Zeb, known in the Philippines as Typhoon Iliang, was a powerful typhoon that struck the island of Luzon in October 1998. It is tied with Cyclone Ron and Cyclone Susan in terms of minimum pressure, for the most intense tropical cyclone worldwide for 1998. The tenth tropical storm of the 1998 Pacific typhoon season, season, Zeb formed on October 10 from the monsoon trough near the Caroline Islands. It moved westward initially and quickly intensified. Zeb's inflow (meteorology), inflow briefly spawned another tropical storm, which it ultimately absorbed. Developing an eye (cyclone), eye, Zeb rapid deepening, rapidly intensified into a Typhoon#Intensity classifications, super typhoon, officially reaching maximum sustained winds of 205 km/h (125 mph); one warning agency estimated winds as high as 285 km/h (180 mph). After reaching peak intensity, the typhoon struck northern Luzon and quickly weakened over land. Turning to the north, Zeb brushed the east ...

Turning to the north, Zeb brushed the east coast of Taiwan at a reduced intensity, and after accelerating to the northeast it moved through Japan. It became e ...

Low Pressure Area
In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies. Winds circle anti-clockwise around lows in the northern hemisphere, and clockwise in the southern hemisphere, due to opposing Coriolis forces. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis. In meteorology, atmospheric divergence aloft occurs in two kinds of places: * The first is in the area on the east side of upper troughs, which form half of a Rossby wave within the Westerlies (a trough with large wavelength that extends through the troposphere). * A second is an area where wind divergence aloft occurs a ...
