Monstrous ocean waves during typhoon Krosa

Transport Reversal Due to Typhoon Krosa in the Taiwan Strait

A comprehensive hydrodynamic model, COMCOT-S, has been aimed at transport reversal in the Taiwan Strait during the period of Typhoon KROSA in 2007. The numerical model is originally based on COMCOT, and a parametric wind model with atmospheric sub-model is imbedded in COMCOT-S for simulating the typhoon-induced currents. The transport characteristics through the Taiwan Strait under the influenc...

Typhoon-Ocean Interaction: The Ocean Response to Typhoons, and Its Feedback to Typhoon Intensity – Synergy of Observations and Model Simulations

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...

Northwestern Pacific typhoon intensity controlled by changes in ocean temperatures

Dominant climatic factors controlling the lifetime peak intensity of typhoons are determined from six decades of Pacific typhoon data. We find that upper ocean temperatures in the low-latitude northwestern Pacific (LLNWP) and sea surface temperatures in the central equatorial Pacific control the seasonal average lifetime peak intensity by setting the rate and duration of typhoon intensification...

Monstrous Moonshine and Monstrous Lie Superalgebras

Invent. Math. 109, 405-444 (1992). Richard E. Borcherds, Department of pure mathematics and mathematical statistics, 16 Mill Lane, Cambridge CB2 1SB, England. We prove Conway and Norton’s moonshine conjectures for the infinite dimensional representation of the monster simple group constructed by Frenkel, Lepowsky and Meurman. To do this we use the no-ghost theorem from string theory to construc...
