Thunderstorm Activity and Typhoon in Western Japan

Typhoon damage on a shallow mesophotic reef in Okinawa, Japan

Little is known about effects of large storm systems on mesophotic reefs. This study reports on how Typhoon 17 (Jelawat) affected Ryugu Reef on Okinawa-jima, Japan in September 2012. Benthic communities were surveyed before and after the typhoon using line intercept transect method. Comparison of the benthic assemblages showed highly significant differences in coral coverage at depths of 25-32 ...

Regional modelling of the western Pacific typhoon season

An ensemble of typhoon events was examined to detect systematic skills and deficiencies of regional atmospheric models in dynamical downscaling these extreme weather phenomena from global reanalyses data. A regional atmospheric model hindcast was computed for the typhoon season 2004 for SE Asia and the western North Pacific. Global reanalyses data were dynamically downscaled to a grid resolutio...

Relationship between typhoon activity and upper ocean heat content

[1] A 44-year mean distribution of tropical cyclone heat potential (TCHP), a measure of the oceanic heat content from the surface to the 26 C-isotherm depth, shows that TCHP is locally high in the western North Pacific (WNP). TCHP varies on interannual time scales and has a relationship with tropical cyclone (TC) activity. The third mode of an empirical orthogonal function analysis of TCHP show...

Shifting communities after­­ typhoon damage on an upper mesophotic reef in Okinawa, Japan

Very few studies have been conducted on the long-term effects of typhoon damage on mesophotic coral reefs. This study investigates the long-term community dynamics of damage from Typhoon 17 (Jelawat) in 2012 on the coral community of the upper mesophotic Ryugu Reef in Okinawa, Japan. A shift from foliose to bushy coral morphologies between December 2012 and August 2015 was documented, especiall...
