Equatorial wave circulation associated with subseasonal convective variability over the subtropical western North Pacific in boreal summer [PDF]
Weather and Climate DynamicsAtmospheric convection over the subtropical western North Pacific (SWNP) during boreal summer varies on timescales of around 10 d, with significant effects on both local and remote circulation.

Observed Linkages Between Marine Heatwaves and Extreme Weather Over Land: A New Zealand Case Study
International Journal of Climatology, EarlyView.Marine heatwaves consistently warm New Zealand's land surface, but rainfall impacts occur only when synoptic systems enable moisture transport. This 38‐year analysis shows MHWs act as thermodynamic background drivers of heat and conditional amplifiers of extreme rainfall events or droughts.

International Journal of Climatology, EarlyView.This study investigates summer Greenland atmospheric blocking using the Lagrangian tracking Python package blocktrack applied to ERA5 reanalysis and CMIP6 models. Two types of blocks—upstream (Northern Canada origin) and retrograding (Northern Atlantic origin)—are distinguished, with upstream blocks driving recent observed frequency increasing trends ...

Existence of eigenvalues of a linear operator pencil in a curved waveguide - localized shelf waves on a curved coast [PDF]
, 2006 The question of the existence of nonpropagating, trapped continental shelf waves (CSWs) along curved coasts reduces mathematically to a spectral problem for a self-adjoint operator pencil in a curved strip.

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.

Oceanic planetary waves in the coupled ocean-atmosphere system [PDF]
, 2005 The propagation of planetary, or Rossby, waves is studied under the effects of different atmospheric couplings. First, analytical matchings are formulated in which a Rossby wave is coupled to different thermodynamical atmospheres, from a simple heat flux

Resonant Forcing of Oceanic and Atmospheric Rossby Waves in (Sub)Harmonic Modes: Climate Impacts
AtmosphereBaroclinic wave resonance, particularly Rossby waves, has attracted great interest in ocean and atmospheric physics since the 1970s. Research on Rossby wave resonance covers a wide variety of phenomena that can be unified when focusing on quasi ...

Rossby Wave and Pure Rotational Wave [PDF]
Journal of the Atmospheric Sciences, 1972 In this note the proof of the relation that exists at the equator between speed of a pure rotational wave and wavelengths of streamlines and trajectory (Asnani1972) has been provided. Also the proof of the idea of Constant Absolute Spin (C.A.S.) trajectory as distinct from Constant Absolute Vorticity (C.A. V.) trajectory developed is presented.
