Typhoon Dolphin's path shows 'explosive' variations, forecasters say

Typhoon Dolphin, located more than 4,000 kilometers from Taiwan, is exhibiting a highly variable path, making its future trajectory uncertain. Weather analysis indicates that a trough interacting with the subtropical high pressure system in the Bering Sea could influence the typhoon's movement over the next three days.

According to the weather enthusiast page "Watching Weather, Seeing Weather," there is a possibility of increased northward movement for Dolphin within this three-day window. However, if the typhoon does not move sufficiently northward during this period, its chances of shifting further north in subsequent days may diminish. This forecast aligns with earlier predictions that the typhoon might turn northward, though current models suggest the trough might not be strong enough to force a significant turn.

Beyond August 2, the typhoon's path becomes more complex. A stronger high-pressure system near the Sea of Japan could steer Dolphin westward. However, after August 6, another trough interacting with the high pressure, combined with the typhoon's own expanding circulation, might create an opportunity for it to turn northward towards the Ryukyu Islands. Conversely, if the subtropical high retreats too quickly, Dolphin could become trapped in a saddle-shaped pressure field, potentially leading to a southwestward shift and a slower speed, resulting in a "dramatically" diverging forecast path.

In terms of intensity, Dolphin has undergone restructuring after reaching its second peak intensity on the evening of July 29. While satellite imagery was initially limited, analysis of upper-level cloud patterns and convection suggests the restructuring is nearing completion. Clearer satellite views are expected around July 31, potentially revealing a well-defined eye and a significant increase in strength, which could determine if Dolphin becomes the strongest typhoon of the year.
