Sm\u00e4ltande polarisar kommer att f\u00f6rsvaga frekvensen och intensiteten av vinterstormsystem som kallas Western Disturbances under detta \u00e5rhundrade med h\u00f6ga utsl\u00e4pp, vilket minskar vinternederb\u00f6rden och sn\u00f6ackumuleringen i Himalaya, som f\u00f6rs\u00f6rjer stora flodsystem i Sydasien. Western Disturbances \u00e4r extratropiska stormar som har sitt ursprung i Medelhavsomr\u00e5det och som f\u00f6r med sig pl\u00f6tsligt regn, sn\u00f6 och dimma till nordv\u00e4stra Indien, Pakistan och Nepal under vinter- och f\u00f6rmonsuns\u00e4songen. De spelar en viktig roll f\u00f6r att uppr\u00e4tth\u00e5lla Himalayas glaci\u00e4rer och vintergr\u00f6dor, inklusive vete, korn, senap, gram och \u00e4rtor. Forskarna simulerade framtida atmosf\u00e4riska cirkulationsm\u00f6nster i modeller som tog h\u00e4nsyn till minskad havsis i Arktis och Antarktis tillsammans med f\u00f6rh\u00f6jda temperaturer vid havsytan. De fann att sm\u00e4ltande havsis f\u00f6rsvagar och breddar den subtropiska jetstr\u00f6mmen och flyttar den n\u00e4rmare ekvatorn, vilket minskar den v\u00e4stra st\u00f6rningsbildningen och minskar stormaktiviteten med n\u00e4stan 19% i Himalaya-regionen. Minskade stormar kan p\u00e5verka vattenresurser, jordbruk och regionala klimatrisker i dessa l\u00e4nder, vilket visar att pol\u00e4ra klimatf\u00f6r\u00e4ndringar kan ha l\u00e5ngtg\u00e5ende effekter p\u00e5 v\u00e4dersystem tusentals kilometer bort.<\/p>\n
