Instead of letting hot air rise and disperse, the high pressure pushes it back down, compressing and warming it further, while also blocking clouds and storms that might otherwise bring relief. The result: day after day of intensifying heat with little to break the cycle. a3tJAId8BnV H5cjVS3lNmU gKMmpItaN4z FLRRBKaKALz dwkaK0qarJE 1NX6wZ0k5Mm ot4v026Qio1 XSmVYICJmFY
