The Great Bakersfield Dust Storm of 1977 (also known as the Southern San Joaquin Valley Dust Storm) was a severe dust storm in the Southern San Joaquin Valley, California. It started in the late evening on December 19, 1977 and ended in the afternoon of December 21. It resulted in 3 deaths and $40 million in damages (does not include subsequent agricultural losses). ==The Great Dust Storm== December 19 started like most cold winter days. At 11:00 pm, temperature was with a light northwestern wind. By 11:30 pm, the weather had started to change. The temperature began to warm up and the wind had shifted direction. It also started to grow in strength and dust started to restrict visibility. In the very early morning, the next day, power was sporadic throughout the city.〔Boyd, Sean.

However, by 9:00 am, school was cancelled. Parents were requested to pick up their children because of the concern that high-profile buses could blow over.〔Maynard, John. ''Bakersfield: A Centennial Portrait''. Cherbo Publishing Group. Encino, California: 1997. ISBN 1-882933-19-2. Pages 89-90.〕 By late morning, the wind was blowing hard, and sounded like a loud roar. Enough dust was in the air that it blocked out the sun. Roads into and out of the southern valley were closed. Only one TV station and two or three AM radio stations continued to have power and were able to broadcast. Also, since Bakersfield did not have a direct feed to national news broadcast, no one outside of the area knew the severity of the situation.〔 Wind continued to blow throughout the afternoon and evening. Swamp coolers were blown off the roofs of buildings. Windows were shattering and store signs were blowing in the wind. It was described as if a twister was unrolled and blew up the valley in a sheet. Farther north in the valley, Fresno was having a typical December rain. When the dust reached the rain, it turned into mud. It fell in sheets from the sky.〔Maynard, John. ''Bakersfield: A Centennial Portrait''. Cherbo Publishing Group. Encino, California: 1997. ISBN 1-882933-19-2. Pages 90-92.〕 People awoke the next morning to a dark sky. The wind had blown throughout the night and was continuing in the morning. Schools remained closed that day. By the afternoon, the wind began to subside, and the air started to clear.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Great Bakersfield Dust Storm of 1977」の詳細全文を読む スポンサード リンク
