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

open access: yesInternational 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

open access: yesMeteorological 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.

Automatic and probabilistic foehn diagnosis with a statistical mixture model [PDF]

open access: yes, 2013
Diagnosing foehn winds from weather station data downwind of topographic obstacles requires distinguishing them from other downslope winds, particularly nocturnal ones driven by radiative cooling.

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

open access: yesQuarterly 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 ...

Dynamics of a Puelche foehn event in the Andes

open access: yesMeteorologische Zeitschrift, 2018
In this numerical modelling study, we investigate a Puelche foehn event (25–26 March 2014) in the southern Andes – a region with sparse observations. The synoptic environment as well as the mesoscale structure and the dynamics of the easterly wind are ...

Observations and numerical simulations of a valley‐exit wind in the Alpine Bolzano basin

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 152, Issue 779, July 2026 Part B.
The evolution and spreading of the nocturnal valley‐exit wind flowing from the Isarco Valley into the Bolzano basin, in the Italian Alps, are found to be influenced by the basin temperature stratification. Measurements and high‐resolution simulations show that a cold‐air pool favors an upward trajectory of the flow at the exit of the valley.

Determination of wind turbine far wake using actuator disk [PDF]

open access: yes, 2014
The growth in size of wind turbines over the last years is significant. The rotor diameter becomes somehow comparable to atmospheric boundary layer at the land surface. In this case the assumption of uniform velocity of upcoming wind cannot be valid. The

A protracted phenology: Post‐diapause larval development of a threatened butterfly

open access: yesInsect Conservation and Diversity, Volume 19, Issue 4, Page 859-872, July 2026.
Larval survival during diapause was high; hibernaculum webs were mostly located near Succisa pratensis plants, which often retained vital leaves through winter. Post‐diapause developmental time varied strongly depending on exposure to different microclimates, being reduced by litter cover, solar radiation and a higher heat load index.
