Water lifting and outflow gain of kinetic energy in tropical cyclones

Autor: Makarieva, Anastassia M., Gorshkov, Victor G., Nefiodov, Andrei V., Chikunov, Alexander V., Sheil, Douglas, Nobre, Antonio Donato, Nobre, Paulo, Plunien, Günter, Molina, Ruben D.

While water lifting plays a recognized role in the global atmospheric power budget, estimates for this role in tropical cyclones vary from no effect to a major reduction in storm intensity. To better assess this impact, here we consider the work outp

Comments on 'An evaluation of hurricane superintensity in axisymmetric numerical models' by Rapha\'el Rousseau-Rizzi and Kerry Emanuel

In a recent paper Rousseau-Rizzi and Emanuel (2019) presented a derivation of an upper limit on maximum hurricane velocity at the surface. This derivation was based on a consideration of an infinitely narrow (differential) Carnot cycle with the warme

Hurricane's maximum potential intensity and surface heat fluxes

Autor: Makarieva, Anastassia M., Gorshkov, Victor G., Nefiodov, Andrei V., Chikunov, Alexander V., Sheil, Douglas, Nobre, Antonio Donato, Nobre, Paulo, Li, Bai-Lian

Emanuel's concept of Maximum Potential Intensity (E-PI) relates the maximum velocity $V_{\rm max}$ of tropical storms, assumed to be in gradient wind balance, to environmental parameters. Several studies suggested that the unbalanced flow is responsi

Hurricane's Maximum Potential Intensity and the Gravitational Power of Precipitation

Autor: Makarieva, A. M., Gorshkov, V. G., Nefiodov, A. V., Chikunov, A. V., Sheil, D., Nobre, A. D., Li, B. -L.

The concept of Maximum Potential Intensity (MPI) is widely used in tropical cyclone research to estimate the minimum central pressure and the maximum velocity of tropical storms from environmental parameters. The MPI pressure derives from considerati

Report

The water budget of a hurricane as dependent on its movement

Autor: Makarieva, Anastassia M., Gorshkov, Victor G., Nefiodov, Andrei V., Chikunov, Alexander V., Sheil, Douglas, Nobre, Antonio D., Li, Bai-Lian

Despite the dangers associated with tropical cyclones and their rainfall, the origins of storm moisture remains unclear. Existing studies have focused on the region 40-400 km from the cyclone center. It is known that the rainfall within this area can
