The Classical Approximation for Real-Time Scalar Field Theory at Finite Temperature [PDF]

, 1998
The use of classical thermal field to approximate real-time quantum thermal field theory is discussed. For a \lambda\phi^4 theory, it is shown that the classical Rayleigh-Jeans divergence can be canceled with the appropriate counterterms, and a ...

A Fast Analytical Model for the Complete Radial Structure of Tropical Cyclone Low‐Level Wind Field

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract A tropical cyclone (TC) can generally be divided into three regions: inner core with vigorous convection, intermediate region with intermittent convection, and far outer region with less convective activity. The different physics in these three regions suggest correspondingly different wind structure models. In this study, we combine the inner‐

The Importance of an Ensemble Approach for Modeling Aerosol‐Convection Interactions

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Aerosol‐convection interactions modulate cloud microphysics, thermodynamics, and updraft intensity, contributing to climate‐scale aerosol‐radiative forcing. However, quantifying aerosol indirect effects in mixed‐phase deep convection remains challenging due to uncertainties in parameterized physics and initial conditions driving nonlinear ...

Delayed Tropical Asian Summer Monsoon Onset in Recent Decades

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract This study reveals that the onset of tropical Asian summer monsoon (TASM) experienced a pronounced interdecadal delay (about one week) after the late‐2000s. Both the large‐scale seasonal transition reflected by EOF analysis and the monsoon onset dates defined by local rainfall exhibited a clear interdecadal change.

Inconsistency Removal of Reduced Bases in Parametric Model Order Reduction by Matrix Interpolation Using Adaptive Sampling and Clustering

International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT Parametric model order reduction by matrix interpolation allows for efficient prediction of the behavior of dynamic systems without requiring knowledge about the underlying parametric dependency. Within this approach, reduced models are first sampled and then made consistent with each other by transforming the underlying reduced bases. Finally,

Quantification of modeling uncertainty in the Rayleigh damping model

Earthquake Engineering & Structural Dynamics
AbstractUnderstanding and accurately characterizing energy dissipation mechanisms in civil structures during earthquakes is an important element of seismic assessment and design. The most commonly used model is attributed to Rayleigh. This paper proposes a systematic approach to quantify the uncertainty associated with Rayleigh's damping model ...
