RISSalinity Variability Associated with the Positive Indian Ocean Dipole and Its Impact on the Upper Ocean Temperature
Publisher: American Meteorological Society
Abstract: AbstractBoth surface and subsurface salinity variability associated with positive Indian Ocean dipole (pIOD) events and its impacts on the sea surface temperature (SST) evolution are investigated through analysis of ...
On the Warm Core of a Tropical Cyclone Formed near the Tropopause
Publisher: American Meteorological Society
Abstract: n the basis of numerical results of a three-dimensional model diagnosed using balance dynamics, a mechanism by which the upper-level warm core of tropical cyclones (TCs) forms is proposed. The numerical results reveal that ...
Annual ENSO
Publisher: American Meteorological Society
Abstract: Using various observational data, the seasonal cycle of the tropical Pacific is investigated, suggesting the existence of an ?annual El Niño?Southern Oscillation (ENSO).? A positive sea surface temperature anomaly (SSTA) ...

Improvements of the Double-Moment Bulk Cloud Microphysics Scheme in the Nonhydrostatic Icosahedral Atmospheric Model (NICAM)
Publisher: American Meteorological Society
Abstract: This study revises the collisional growth, heterogeneous ice nucleation, and homogeneous ice nucleation processes in a double-moment bulk cloud microphysics scheme implemented in the Nonhydrostatic Icosahedral Atmospheric ...
Multiyear ENSO Dynamics as Revealed in Observations, Climate Model Simulations, and the Linear Recharge Oscillator
Publisher: American Meteorological Society
Abstract: El Niño–Southern Oscillation (ENSO) events occasionally recur one after the other in the same polarity, called multiyear ENSO. However, the dynamical processes are not well understood. This study aims to elucidate the ...
Active Learning–Based Estimation of Extreme Roll Motion in Beam Seas with Supervised Dimensionality Reduction and Gradient Approximation
Publisher: American Society of Civil Engineers
Abstract: AbstractAn efficient method is presented for estimating extreme nonlinear roll motion of a
ship in beam seas in a given short-term sea state. With the aim of reducing the number
of numerical simulations for roll motion ...
Warm Cores, Eyewall Slopes, and Intensities of Tropical Cyclones Simulated by a 7-km-Mesh Global Nonhydrostatic Model
Publisher: American Meteorological Society
Abstract: ased on the data of a 1-yr simulation by a global nonhydrostatic model with 7-km horizontal grid spacing, the relationships among warm-core structures, eyewall slopes, and the intensities of tropical cyclones (TCs) were ...
Seasonal Variation of the Seychelles Dome
Publisher: American Meteorological Society
Abstract: Using an ocean general circulation model (OGCM), seasonal variation of the Seychelles Dome (SD) is investigated for the first time. The SD is an oceanic thermal dome located in the southwestern Indian Ocean, and its influence ...
The Atlantic Meridional Mode and Its Coupled Variability with the Guinea Dome
Publisher: American Meteorological Society
Abstract: Using an ocean?atmosphere coupled general circulation model, air?sea interaction processes associated with the Atlantic meridional mode are investigated from a new viewpoint of its link with the Guinea Dome in the northern ...
