Summary
[edit]DescriptionDust storm in Iraq, Kuwait, and Saudi Arabia (MODIS 2017-11-04).jpg |
English: The large dust storm that darkened the skies over much of Iraq, Kuwait, and Saudi Arabia in the last week of October 2017 continued into the opening days of November. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired this true-color image of dust blowing over all three countries on November 1.
The dust had been aloft for several days by the time this image was captured. At 7 a.m. local time on October 30, the storm had reduced visibility in parts of Iraq to just 600 meters, according to news reports. As a result, the Iraqi Civil Aviation Authority temporarily suspended air traffic until conditions improved. The dust was also reported to have damaged refugee shelters and spurred breathing problems in northern Iraq. On October 31 the dust storm heavily engulfed Kuwait and the Persian Gulf. Ship traffic at Shuwaikh Port came to a halt as visibility dropped to just 500 meters. Meteorologists in Kuwait noted that pressure changes this time of year typically bring quick, dramatic shifts in the weather. This dust storm was carried by relatively cool winds. As air temperatures drop, meteorologists expected the winds and dust to slowly diminish. Multi-day dust storms in the Middle East are often spurred by the shamal, a pattern of persistent winds that blow toward the southeast (northwesterly winds). Shamal winds are most frequent in June and July, but can happen any time of year. Conversely, the gale-force kaus, or sharki, winds blow toward the northwest (southeasterly winds) and typically occur between December and April. According to a 2013 research paper, published in Natural Science, the frequency of dust storms in the Iraq have been increasing over the past decade. The authors cite reduced rainfall as one of the main reasons, as well as land degradation and desertification. |
