  text: Current knowledge suggests a drought Indian monsoon (perhaps a severe one)
    when the El Nino Southern Oscillation and Pacific Decadal Oscillation each exhibit
    positive phases (a joint positive phase). For the monsoons, which are exceptions
    in this regard, we found northeast India often gets excess pre-monsoon rainfall.
    Further investigation reveals that this excess pre-monsoon rainfall is produced
    by the interaction of the large-scale circulation associated with the joint phase
    with the mountains in northeast India. We posit that a warmer troposphere, a consequence
    of excess rainfall over northeast India, drives a stronger monsoon circulation
    and enhances monsoon rainfall over central India. Hence, we argue that pre-monsoon
    rainfall over northeast India can be used for seasonal monsoon rainfall prediction
    over central India. Most importantly, its predictive value is at its peak when
    the Pacific Ocean exhibits a joint positive phase and the threat of extreme drought
    monsoon looms over India.

  text: The elimination of rain evaporation in the planetary boundary layer (PBL)
    has been found to lead to convective self‐aggregation (CSA) even without radiative
    feedback, but the precise mechanisms underlying this phenomenon remain unclear.
    We conducted cloud‐resolving simulations with two domain sizes and progressively
    reduced rain evaporation in the PBL. Surprisingly, CSA only occurred when rain
    evaporation was almost completely removed. The additional convective heating resulting
    from the reduction of evaporative cooling in the moist patch was found to be the
    trigger, thereafter a dry subsidence intrusion into the PBL in the dry patch takes
    over and sets CSA in motion. Temperature and moisture anomalies oppose each other
    in their buoyancy effects, hence explaining the need for almost total rain evaporation
    removal. We also found radiative cooling and not cold pools to be the leading
    cause for the comparative ease of CSA to take place in the larger domain.

  text: The presence of a developed boundary layer decouples a glacier's response
    from ambient conditions, suggesting that sensitivity to climate change is increased
    by glacier retreat. To test this hypothesis, we explore six years of distributed
    meteorological data on a small Swiss glacier in the period 2001–2022. Large glacier
    fragmentation has occurred since 2001 (−35% area change up to 2022) coinciding
    with notable frontal retreat, an observed switch from down‐glacier katabatic to
    up‐glacier valley winds and an increased sensitivity (ratio) of on‐glacier to
    off‐glacier temperature. As the glacier ceases to develop density‐driven katabatic
    winds, sensible heat fluxes on the glacier are increasingly determined by the
    conditions occurring outside the boundary layer of the glacier, sealing the glacier's
    demise as the climate continues to warm and experience an increased frequency
    of extreme summers.

  text: The sensitivity of coarse-grained daily extreme precipitation to sea surface
    temperature is analyzed using satellite precipitation estimates over the 300–302.5
    K range. A theoretical scaling is proposed, linking changes in coarse-grained
    precipitation to changes in fine-scale hourly precipitation area fraction and
    changes in conditional fine-scale precipitation rates. The analysis reveals that
    the extreme coarse-grained precipitation scaling with temperature (∼7%/K) is dominated
    by the fine-scale precipitating fraction scaling (∼6.5%/K) when using a 3 mm/h
    fine-scale threshold to delineate the precipitating fraction. These results are
    shown to be robust to the selection of the precipitation product and to the percentile
    used to characterize the extreme. This new coarse-grained scaling is further related
    to the well-known scaling for fine-scale precipitation extremes, and suggests
    a compensation between thermodynamic and dynamic contributions or that both contributions
    are small with respect to that of fractional coverage. These results suggest that
    processes responsible for the changes in fractional coverage are to be accounted
    for to assess the sensitivity of coarse-grained extreme daily precipitation to
    surface temperature.

  text: Squall lines are known to be the consequence of the interaction of low-level
    shear with cold pools associated with convective downdrafts. Also, as the magnitude
    of the shear increases beyond a critical shear, squall lines tend to orient themselves.
    The existing literature suggests that this orientation reduces incoming wind shear
    to the squall line, and maintains equilibrium between wind shear and cold pool
    spreading. Although this theory is widely accepted, very few quantitative studies
    have been conducted on supercritical regime especially. Here, we test this hypothesis
    with tropical squall lines obtained by imposing a vertical wind shear in cloud
    resolving simulations in radiative convective equilibrium. In the sub-critical
    regime, squall lines are perpendicular to the shear. In the super-critical regime,
    their orientation maintain the equilibrium, supporting existing theories. We also
    find that as shear increases, cold pools become more intense. However, this intensification
    has little impact on squall line orientation.

  text: The thinning patterns of debris-covered glaciers in High Mountain Asia are
    not well understood. Here we calculate the effect of supraglacial ice cliffs on
    the mass balance of all glaciers in a Himalayan catchment, using a process-based
    ice cliff melt model. We show that ice cliffs are responsible for higher than
    expected thinning rates of debris-covered glacier tongues, leading to an underestimation
    of their ice mass loss of 17% ± 4% in the catchment if not considered. We also
    show that cliffs do enhance melt where other processes would suppress it, that
    is, at high elevations, or where debris is thick, and that they contribute relatively
    more to glacier mass loss if oriented north. Our approach provides a key contribution
    to our understanding of the mass losses of debris-covered glaciers, and a new
    quantification of their catchment wide melt and mass balance.

  text: Glaciers in the high mountains of Asia provide an important water resource
    for millions of people. Many of these glaciers are partially covered by rocky
    debris, which protects the ice from solar radiation and warm air. However, studies
    have found that the surface of these debris-covered glaciers is actually lowering
    as fast as glaciers without debris. Water ponded on the surface of the glaciers
    may be partially responsible, as water can absorb atmospheric energy very efficiently.
    However, the overall effect of these ponds has not been thoroughly assessed yet.
    We study a valley in Nepal for which we have extensive weather measurements, and
    we use a numerical model to calculate the energy absorbed by ponds on the surface
    of the glaciers over 6 months. As we have not observed each individual pond thoroughly,
    we run the model 5,000 times with different setups. We find that ponds are extremely
    important for glacier melt and absorb energy 14 times as quickly as the debris-covered
    ice. Although the ponds account for 1% of the glacier area covered by rocks, and
    only 0.3% of the total glacier area, they absorb enough energy to account for
    one eighth of the whole valley's ice loss.
