🚨⚡️#Shiveluch #Volcano in Kamchatka-Russia has erupted twice within the last 48 hours, with both eruptions reaching near-stratospheric altitudes. Will such volcanic activity affect our next Autumn and Winter weather? The short answer is: Yes, that is plausible. But , Why and How? Several reasons. Although Kamchatka is located in the mid-latitudes rather than the tropics, such major eruptions may still exert a measurable influence on the terrestrial climate for several reasons: a) Both eruptions were powerful enough to inject substantial amounts of ash and aerosols into the upper troposphere and near the stratosphere. Successive eruptions can produce cumulative climatic effects. Notably, the major Ethiopian eruption of late 2025 (Lyo Gobi/Hayli Gubbi), which reportedly lofted material to nearly 30 km altitude, occurred only a few months ago ( November 2025) . b) The climatic imprint of such substantive eruptions (with VEI >=4 )may persist for at least 24 months. Their weather impact usually appears( as cooling) in less than 6-8 weeks. c) Volcanic eruptions occurring east of major continental landmasses can, under certain atmospheric configurations, exert a climatic forcing comparable to some equatorial eruptions. Additionally, the stratosphere is lower in the mid-latitudes than in the tropics, making stratospheric injection more attainable for sufficiently explosive eruptions. d) Published scientific evidence suggests that major volcanic eruptions occurring near, or shortly before, the middle of the year often have a greater likelihood of influencing the subsequent winter season through their impacts on atmospheric circulation. To me, the timing of those substantive volcanic eruptions ( Just around mid-year ) adds extra weight to their possible impact on next winter more than the other reasons. e) We do Not know what other eruptions are coming ahead the coming few months, the more of those VEI=4 eruptions we get the greater the cumulative effect on the terrestrial weather. A tentative conclusion is that we had the three substantive eruptions observed during the past seven months may collectively influence the upcoming winter, regional cooling in the NH is possible for some parts of Europe and Asia . One plausible pathway is through modifications to large-scale atmospheric circulation patterns, including effects on the Walker Circulation and related teleconnection systems. Impact differs from region to another, no fixed cooling impact across land.

Look at this OLR anomaly chart on a seasonal time scale What indices would explain this rainfall variability over EQ IO??. Traditional IOD/ENSO indices are said to be neutral but the Indian ocean atmosphere was more like a weak IOD, EQUINOO. So any teleconnections ?? Intensity of the dry anomalies over EIO appears strong ,dominating the global Tropics. Is this a cause or an effect ?? Even during active MJO phase 3,4,5 convective cycle , EIO wasn't active like how it used to be. Suppression had an upper hand throughout the season.

An excellent analogy for #Climatevariability vs #climatechange to a man walking his dog. Much more variation in the path that the dog takes as compared to man, but both are headed the same way! Nice talk by Stephanie Dickson, BoM at #GRDCUpdates @GRDCWest
