“This work highlight that the large interannual variability in glacier mass balance is largely associated with fluctuations in accumulation and ablation driven by extreme precipitation events across the Himalaya. These events can temporarily offset annual ice losses by enhancing snow accumulation…”
--
“HIGHLIGHTS:
• Annual-to-decadal relationships between glacier surface mass balance and extreme precipitation events (EPEs) were identified and analyzed for the western Himalaya.
• Although negative mass balance dominates in the region, extreme precipitation events (0–5/year) are linked to less negative and positive mass balance years through increased snowfall.
• NAO/AO phases increase Western Disturbance frequency/intensity, promoting accumulation; Western Disturbances (60.2%) control EPEs with wintertime snowfall.
ABSTRACT: Extreme precipitation events can drive anomalous snow accumulation on Himalayan glaciers, thereby affecting short-term variations in mass balance. Over the past five decades, an accelerated mass loss of Himalayan glaciers has been observed, making it critical to assess the role of precipitation, particularly extreme events in modulating glacier health. This study compiles 182 in situ glacier-wide mass-balance observations from 26 glaciers in the western Himalaya, India, from 1974 to 2023. Observing an alarming negative cumulative mass balance of around −26 ± 1.67 m w.e., with more frequent years in recent decades showing negative mass balance exceeding −1.5 m w.e. / a, highlights the ongoing severity of glacier mass loss. However, over several years, there have been relative mass-balance gains or reduced losses, often linked to extreme precipitation events (EPEs), with annual fluctuations between 0 and 5 events. Cross-correlation analysis supports this, showing a direct response of glacier mass balance to EPEs variability. The EPEs are mainly fed by moisture supply from Western Disturbances (60.2%), followed by the Indian Summer Monsoon (16.4%), cyclogenesis (6.3%), and WD–cyclogenesis interactions (4.6%), while other synoptic systems account for the remaining ∼12%, together driving strong moisture convergence and severe precipitation episodes. These synoptic drivers determine the frequency and intensity of EPEs and influence the precipitation phase snow versus rain, thus impacting accumulation and melt processes differently. Statistical evidence indicates that EPEs temporarily increase accumulation, counteracting seasonal mass losses in certain years with moderate same-year sensitivity…”

🌍 Pushing #ClimateModeling to the Next Level
What happens when you run global climate #simulations at the kilometre scale for multiple years
In our latest blog post, we share insights from a landmark #nextGEMS study using ECMWF’s Integrated Forecasting System coupled to high-resolution ocean–sea ice models.
These simulations capture fine-scale processes—from mesoscale #OceanEddies to #UrbanHeat patterns—that coarser models can’t resolve, offering a more realistic picture of our climate system. Along the way, the team tackled key challenges, from water and #EnergyConservation to improving the simulation of #ExtremePrecipitation and polar sea ice leads.
💡 The results point towards more accurate, actionable climate information—but also highlight the huge computational demands of this frontier.

Anthropogenic amplification of precipitation variability over the past century
Wenxia Zhang, Tianjun Zhou , and Peili Wu
25 Jul 2024
Abstract
"As the climate warms, the consequent moistening of the atmosphere increases #ExtremePrecipitation. #Precipitation variability should also increase, producing larger wet-dry swings, but that is yet to be confirmed observationally. Here we show that precipitation variability has already grown globally (over 75% of land area) over the past century, as a result of accumulated #anthropogenic warming. The increased variability is seen across daily to intraseasonal timescales, with daily variability increased by 1.2% per 10 years globally, and is particularly prominent over Europe, Australia, and eastern North America. Increased precipitation variability is driven mainly by thermodynamics linked to atmospheric moistening, modulated at decadal timescales by circulation changes. Amplified precipitation variability poses new challenges for weather and climate predictions, as well as for resilience and adaptation by societies and #ecosystems."https://www.science.org/doi/10.1126/science.adp0212

"On Thursday, October 17, six French departments south of Lyon faced "exceptional" rainfall of up to 650 millimeters. A torrent raged over the city of Annonay, with cars submerged and firefighters in diving suits. Aurélien Ribes, a researcher at Météo-France's National Center for Meteorological Research, points out that this phenomenon is likely to recur with #ClimateChange."

To spell it out for the #US east coast: Heat lingers more south of Florida where #hurricanes can pick up more power and more moisture, faster, so #RapidIntensification.
As they travel north, that moisture comes down as #ExtremePrecipitation, meaning record #rain.
Meanwhile #StormSurge is whipped up by stronger winds in the hurricane. And gets amplified by the #SeaLevelRise from the slowed ocean current.
Batten down the hatches, East Coast.

Once-a-century extreme precipitation could occur every 30 years in the US by 2100, according to a new study. The researchers used climate models and historical data to project how the frequency and intensity of heavy rainfall events will change under different warming scenarios. The study warns that such events could pose serious risks for flooding, infrastructure damage, and public health, especially in urban areas.
