  text: The near-surface boundary layer can mediate the response of mountain glaciers
    to external climate, cooling the overlying air and promoting a density-driven
    glacier wind. The fundamental processes are conceptually well understood, though
    the magnitudes of cooling and presence of glacier winds are poorly quantified
    in space and time, increasing the forcing uncertainty for melt models. We utilize
    a new data set of on-glacier meteorological measurements on three neighboring
    glaciers in the Swiss Alps to explore their distinct response to regional climate
    under the extreme 2022 summer. We find that synoptic wind origins and local terrain
    modifications, not only glacier size, play an important role in the ability of
    a glacier to cool the near-surface air. Warm air intrusions from valley or synoptically-driven
    winds onto the glacier can occur between ∼19% and 64% of the time and contribute
    between 3% and 81% of the total sensible heat flux to the surface during warm
    afternoon hours, depending on the fetch of the glacier flowline and its susceptibility
    to boundary layer erosion. In the context of extreme summer warmth, indicative
    of future conditions, the boundary layer cooling (up to 6.5°C cooler than its
    surroundings) and resultant katabatic wind flow are highly heterogeneous between
    the study glaciers, highlighting the complex and likely non-linear response of
    glaciers to an uncertain future.

  text: Peruvian glaciers are important contributors to dry season runoff for agriculture
    and hydropower, but they are at risk of disappearing due to climate change. We
    applied a physically based, energy balance melt model at five on-glacier sites
    within the Peruvian Cordilleras Blanca and Vilcanota. Net shortwave radiation
    dominates the energy balance, and despite this flux being higher in the dry season,
    melt rates are lower due to losses from net longwave radiation and the latent
    heat flux. The sensible heat flux is a relatively small contributor to melt energy.
    At three of the sites the wet season snowpack was discontinuous, forming and melting
    within a daily to weekly timescale, and resulting in highly variable melt rates
    closely related to precipitation dynamics. Cold air temperatures due to a strong
    La Niña year at Shallap Glacier (Cordillera Blanca) resulted in a continuous wet
    season snowpack, significantly reducing wet season ablation. Sublimation was most
    important at the highest site in the accumulation zone of the Quelccaya Ice Cap
    (Cordillera Vilcanota), accounting for 81% of ablation, compared to 2%–4% for
    the other sites. Air temperature and precipitation inputs were perturbed to investigate
    the climate sensitivity of the five glaciers. At the lower sites warmer air temperatures
    resulted in a switch from snowfall to rain, so that ablation was increased via
    the decrease in albedo and increase in net shortwave radiation. At the top of
    Quelccaya Ice Cap warming caused melting to replace sublimation so that ablation
    increased nonlinearly with air temperature.

  text: 'Expected changes to future extreme precipitation remain a key uncertainty
    associated with anthropogenic climate change. Extreme precipitation has been proposed
    to scale with the precipitable water content in the atmosphere. Assuming constant
    relative humidity, this implies an increase of precipitation extremes at a rate
    of about 7% °C−1 globally as indicated by the Clausius‐Clapeyron relationship.
    Increases faster and slower than Clausius‐Clapeyron have also been reported. In
    this work, we examine the scaling between precipitation extremes and temperature
    in the present climate using simulations and measurements from surface weather
    stations collected in the frame of the HyMeX and MED‐CORDEX programs in Southern
    France. Of particular interest are departures from the Clausius‐Clapeyron thermodynamic
    expectation, their spatial and temporal distribution, and their origin. Looking
    at the scaling of precipitation extreme with temperature, two regimes emerge which
    form a hook shape: one at low temperatures (cooler than around 15°C) with rates
    of increase close to the Clausius‐Clapeyron rate and one at high temperatures
    (warmer than about 15°C) with sub‐Clausius‐Clapeyron rates and most often negative
    rates. On average, the region of focus does not seem to exhibit super Clausius‐Clapeyron
    behavior except at some stations, in contrast to earlier studies. Many factors
    can contribute to departure from Clausius‐Clapeyron scaling: time and spatial
    averaging, choice of scaling temperature (surface versus condensation level),
    and precipitation efficiency and vertical velocity in updrafts that are not necessarily
    constant with temperature. But most importantly, the dynamical contribution of
    orography to precipitation in the fall over this area during the so‐called “Cevenoles”
    events, explains the hook shape of the scaling of precipitation extremes.'

  text: Air temperature is one of the most relevant input variables for snow and ice
    melt calculations. However, local meteorological conditions, complex topography,
    and logistical concerns in glacierized regions make the measuring and modeling
    of air temperature a difficult task. In this study, we investigate the spatial
    distribution of 2 m air temperature over mountain glaciers and propose a modification
    to an existing model to improve its representation. Spatially distributed meteorological
    data from Haut Glacier d'Arolla (Switzerland), Place (Canada), and Juncal Norte
    (Chile) Glaciers are used to examine approximate flow line temperatures during
    their respective ablation seasons. During warm conditions (off-glacier temperatures
    well above 0°C), observed air temperatures in the upper reaches of Place Glacier
    and Haut Glacier d'Arolla decrease down glacier along the approximate flow line.
    At Juncal Norte and Haut Glacier d'Arolla, an increase in air temperature is observed
    over the glacier tongue. While the temperature behavior over the upper part can
    be explained by the cooling effect of the glacier surface, the temperature increase
    over the glacier tongue may be caused by several processes induced by the surrounding
    warm atmosphere. In order to capture the latter effect, we add an additional term
    to the Greuell and Böhm (GB) thermodynamic glacier wind model. For high off-glacier
    temperatures, the modified GB model reduces root-mean-square error up to 32% and
    provides a new approach for distributing air temperature over mountain glaciers
    as a function of off-glacier temperatures and approximate glacier flow lines.

  text: Parameterizations of incoming longwave radiation are increasingly receiving
    attention for both low and high elevation glacierized sites. In this paper, we
    test 13 clear-sky parameterizations combined with seven cloud corrections for
    all-sky atmospheric emissivity at one location on Haut Glacier d'Arolla. We also
    analyze the four seasons separately and conduct a cross-validation to test the
    parameters’ robustness. The best parameterization is the one by Dilley and O'Brien,
    B for clear-sky conditions combined with Unsworth and Monteith cloud correction.
    This model is also the most robust when tested in cross-validation. When validated
    at different sites in the southern Alps of Switzerland and north-western Italian
    Alps, all parameterizations show a substantial decrease in performance, except
    for one site, thus suggesting that it is important to recalibrate parameterizations
    of incoming longwave radiation for different locations. We argue that this is
    due to differences in the structure of the atmosphere at the sites. We also quantify
    the effect that the incoming longwave radiation parameterizations have on energy-balance
    melt modeling, and show that recalibration of model parameters is needed. Using
    parameters from other sites leads to a significant underestimation of melt and
    to an error that is larger than that associated with using different parameterizations.
    Once recalibrated, however, the parameters of most models seem to be stable over
    seasons and years at the location on Haut Glacier d'Arolla.
