Outracing a National Level Model Racing Car Champion: A Hybrid Model‐Based Data‐Driven Approach

Journal of Field Robotics, EarlyView.
ABSTRACT This paper discusses lap time optimization, focusing on a single lap without considering opponents in autonomous racing. The paper presents a control and optimization architecture composed of a model‐based low level controller and a higher level iterative learning algorithm with the goal of obtaining the fastest qualifying lap in autonomous ...

Characteristic Features of the Antarctic Surface Air Temperature with Different Reanalyses and In Situ Observations and Their Uncertainties

Atmosphere, 2023
Antarctic surface air temperature (SAT) variability is characterized by strong seasonality and regionality, which are associated with the tropical–polar teleconnections and the radiative forcing caused by the concentration changes in ozone and other ...

How weather got its words: a history of meteorological English – Part 1: Old English to the Age of Discovery

Weather, EarlyView.
The English language is a gargantuan, gluttonous beast. It has become extraordinary among its peers in its powers of assimilation – such that we rarely consider the diverse origins of the words we use. In this two‐part paper, we will explore these origins, including the Pontic‐Caspian steppe, the British Empire, latinophone scientists and a TV show. We

Atmospheric River‐Cyclone Events Disrupting an Antarctic Peninsula Field Campaign: Dynamics, Mesoscale Wind Amplification, and Long‐Term Context

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Extreme weather in the Antarctic Peninsula arises from interactions among large‐scale circulation variability, atmospheric rivers (ARs), extratropical cyclones, and complex coastal terrain, yet the linkages across these scales remain insufficiently resolved.

Objective Forecasting of Foehn Winds for a Subgrid-Scale Alpine Valley

Weather and Forecasting, 2008
Abstract Foehn winds often depend on topographical features of a scale that is not sufficiently resolved in numerical models. Consequently, a successful foehn forecast has crucially depended on the experience of bench forecasters. This study provides a method for an objective, probabilistic forecast of foehn occurrence and strength ...

Distinct El Niño Flavors and SAM Variability Modulate Surface Melt Over the Ross Ice Shelf

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Our study investigates how different flavors of El Niño, centered on the Eastern Pacific (EP) and Central Pacific (CP), and their interaction with the Southern Annular Mode (SAM) modulate surface melt events over the Ross Ice Shelf (RIS). Using satellite‐based melt observations, ERA5 reanalysis, high‐resolution regional model simulations, and ...

Decadal Changes of UV Aerosol Optical Depth in Hobart, Australia Measured With a Brewer MKIII: Relationship to Bushfire Events and Climate Indices

International Journal of Climatology, Volume 46, Issue 9, July 2026.
Monthly average aerosol optical depth at 320 nm obtained with a Brewer MKIII spectrophotometer for Hobart, Australia (42.8806° S, 147.3250° E) over a 21‐year period. There is a linear trend of 15.4% per decade. There are 9 months when the average aerosol optical depth exceeds twice the monthly standard deviation.

Near‐Surface Air Temperature Measurements: Contribution to the Overall Uncertainty due to Wind Speed and Relative Humidity

Meteorological Applications, Volume 33, Issue 4, July/August 2026.
This work evaluates the uncertainties on air temperature measurements from ground‐based stations under real environmental conditions, addressing the environment effects component, required by the World Meteorological Organisation to include in the overall measurement uncertainty.

Suggestions for unifying the parametrizations of turbulent orographic form drag, mountain wave drag, and flow blocking

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 778, July 2026 Part A.
A theory for the interaction between a boundary layer and a low mountain is used to provide estimates of the turbulent orographic form drag, upward‐propagating mountain gravity‐wave drag, and trapped lee‐wave drag (case shown in the figure). After reviewing briefly how these processes are represented in weather and climate models, we propose a ...
