Final answer:
The approximate yearly frequency of tropical revolving storms in the Southwest Pacific, east of Australia, is 15-20 storms. Increased strength of winds and precipitation associated with storms is likely, affecting patterns in this region. The Philippine Islands experience a similar frequency, emphasizing the region's susceptibility to these severe weather events.
Step-by-step explanation:
The frequency of tropical revolving storms (TRS) in the Southwest Pacific, east of Australia, is an important figure for climatological studies and understanding weather patterns. The correct answer to the question regarding the approximate yearly frequency of TRS in this area is 15-20 storms.
In other related discussions, it has been indicated that the strength of the winds and precipitation associated with tropical storms are likely to increase, potentially affecting storm frequency and severity.
The Philippine Islands, for example, are in the center of the Western Pacific's major typhoon belt and experience as many as 20 typhoons each year, with about half of these making a direct impact on the islands. This area's high frequency of severe weather events, including storms and typhoons, underscores the need for accurate monitoring and understanding of TRS patterns.
