An Omega block, named after the Greek letter because of its shape in the upper atmosphere, prevents cooler weather systems from moving in. As a result, hot, dry air remains trapped beneath the high-pressure system, allowing temperatures to climb day after day.\u00a0<\/p> <p>Meteorologists say this setup has repeatedly emerged over Europe since late May, contributing first to the late-May heatwave and then to the historic late-June event.\u00a0<\/p> <p><strong>Dry soils could amplify temperatures\u00a0<\/strong><\/p> <p>One of the biggest differences this time is the condition of Europe&#8217;s landscape.\u00a0<\/p> <p>The June heatwave has already left large parts of western Europe with severely depleted soil moisture. Normally, some of the Sun&#8217;s energy is used to evaporate water from the ground, providing a natural cooling effect.
