Them to leave it now. they can talk to me on the phone, it s not life or death. it will be if they don t get out, they may not get out. let s get a better understanding of this. paul pastelok is the expert senior meteorolgist at accuweather. what is a weather bomb and what s causing it? here s the thing, president biden hitting the notes, this is a life and death situation for parts of the country. it hasn t formed yet, it hasn t come together yet, but we are seeing the other parts of this winter storm, notjust know, it s the wind and the dramatic change in cold that is taking place. in iowa, at the moment, they are sitting at about minus 10 15, in iowa, at the moment, they are sitting at about minus 10 15 , and the winds are blowing so fast it s
Of the jet stream at around 30,000 feet or so. a disturbance in the powerful jet stream forces the air aloft to accelerate away, removing air from the top of the column. the column weighs less and so the force it is exerting on the ground, the pressure gets lower. hence, low pressure. near the ground, air rushes in to replace what is lost higher up, and the area of low pressure rotates more and more quickly. and as the process continues, the storm is able to deepen explosively. on a weather chart, you will see more and more isobars appearing, like a dartboard, and if the pressure falls by at least 2a millibars in 2a hours, that is explosive cyclogenesis, or a weather bomb. weather bombs like storm eunice are not that unusual. but it is when explosive cyclogenesis happens near land that their impact can be extreme. eunice s winds were so strong they shredded part of the fabric roof of london s
Now, imagine a column of air from the ground up to the level of the jet stream at around 30,000 feet or so. a disturbance in the powerful jet stream forces the air aloft to accelerate away, removing air from the top of the column. the column weighs less and so the force it is exerting on the ground, the pressure gets lower. hence, low pressure. near the ground, air rushes in to replace what is lost higher up, and the area of low pressure rotates more and more quickly. and as the process continues, the storm is able to deepen explosively. on a weather chart, you will see more and more isobars appearing, like a dartboard, and if the pressure falls by at least 2a millibars in 2a hours, that is explosive cyclogenesis, or a weather bomb. weather bombs like storm eunice are not that unusual. but it is when explosive cyclogenesis happens near land that their impact can be extreme. eunice s winds were so strong

The column weighs less and so the force it is exerting on the ground, the pressure, gets lower. hence, low pressure. nearthe ground, air rushes in to replace what is lost higher up, and the area of low pressure rotates more and more quickly. and as the process continues, the storm is able to deepen explosively. on a weather chart, you will see more and more isobars appearing, like a dartboard, and if the pressure falls by at least 2a millibars in 2a hours, that is explosive cyclogenesis, or a weather bomb. weather bombs like storm eunice are not that unusual. but it is when explosive cyclogenesis happens near land their impact can be extreme. eunice s winds were so strong they shredded part of the fabric roof of london s o2 arena, which opened as the millennium dome 22 years ago. dudley was the first of the three named storms to hit the uk injust one week in february. even a wind turbine
