Volcanoes affect Cyclones?

This article is discussing about gasses from Kilauea volcano in Hawaii which affected Tropical storm Flossie last year. What do you guys think of this? It's very rare but can large volcanic ash eruptions affect nearby Tropical Cyclones?

I think cyclones may be more related with earthquakes than volcanoes. In WP for example, sometimes earthquakes happen within days when a Tropical disturbance, tropical storm or a typhoon passes the area. Don't know if cyclones are a factor that triggeres earthquakes.

Any volcanoes about to erupt now? They have Iselle coming.

If the anomalously low atmospheric pressures within hurricanes can trigger ground movement and earthquakes, then I presume volcanic eruptions could be triggered too. As for a volcanic eruption disrupting a hurricane that is also possible. If Saharan dust can do it, so can volcanic ash. However I don't know if Hawaii is the best example for a study, since hurricanes are very rare there and are usually already weakening due to other causes. Atmospheric shear, borderline SSTs, and the extreme altitude of Mauna Loa & Mauna Kea were all disrupting Flossie for instance. Plus, Kilauea is not known as a very "ashy" volcano, its basaltic' lava flows very smoothly without large pressurekeg explosions propelling particulates into the atmosphere. I think that the Philippines might be a preferable location to examine for these theories!

Kilauea has been constantly erupting since 1983.

Now that I reread it I see the article mentions gases more specifically than just solid particulates. This is interesting stuff, though I think the effects would be limited to lightning and precipitation rates and not the overall cyclone, I'm just tossing uneducated thoughts out there.

I'm wondering if there will be any kind of effects when Iselle passes by.

happened in the Philippines...the Climax of Mt. Pinatubo eruption coincided with the landfall of Typhoon Yunya in Luzon...

I don't know if you meant cyclones trigerring volcanic activity, but I can say it's the other way around. Mt. Pinatubo was already erupting before the typhoon came, and Yunya considerably weakened from a Cat3 to a weak TS as it emerged in South China Sea.. the damage though was aggreviated because volcanic materials mixed with heavy rain that was distributed by typhoon-force wind across much of Luzon.

I wasn't in Manila when it happened, but the idea of a volcano/typhoon combo is unbearable... There are vids on Youtube showing this event...

Lahars are when ash and rain mix. The resulting "mudslide" is horrible, as the stuff has the consistency of wet cement and is very heavy. Rain and ash mixing has caused many, many roof collapses over the years in various countries.

Impressive photo showing Typhoon Yunya passing over the eruption of Mount Pinatubo...Ash clouds way up there!
