& ON THE MORNING of September 1, 2019, during the days when people in the Southeastern coast of the United States were preparing for the likely impact of hurricane Dorian, President Donald J. Trump sent a puzzling tweet. Trump wrote that “In addition to Florida––South Carolina, North Carolina, Georgia, and Alabama, will most likely be hit (much) harder than anticipated.” The problem was that the National Hurricane Center’s (NHC) forecast map issued a few hours earlier the same morning, at 5 AM, had the cone of uncertainty quite far from Alabama [see Figure 1]. The President’s tweet caused alarm among Alabamians;many of them, feeling confused andworried began calling the Birmingham office of the NHC, forcing it to tweet a correction: “Alabama will NOT see any impacts from #Dorian. We repeat, no impacts from Hurricane Dorian will be felt across Alabama. The systemwill remain too far east.” Mentioning Alabama in the tweet was certainly a mistake. There is always a 30% chance that the position of a hurricane center will end up outside of the NHC’s cone of uncertainty at some point, but in the morning of September 1, the chances of Dorian’s hitting Alabama “harder than anticipated” in the following days were negligible. The Westernmost boundary of the cone was very far from Alabama’s Southeastern tip. Even so, President Trump refused to issue a correction or apology. Instead, he repeatedly doubled-down. In a White House briefing on September 4th, he tried to prove that there was Digital Object Identifier 10.1109/MCG.2019.2961716

2019 年 9 月 1 日上午,在美国东南海岸的人们为多里安飓风可能带来的影响做准备的日子里,唐纳德·J·特朗普总统发了一条令人费解的推文。特朗普写道:“除了佛罗里达州——南卡罗来纳州、北卡罗来纳州、佐治亚州和阿拉巴马州,很可能会受到比预期更严重的打击。” 问题在于,美国国家飓风中心 (NHC) 的预报图在同一个早上几小时前发布,即凌晨 5 点,在离阿拉巴马州很远的地方存在不确定性锥体 [见图 1]。总统的推文引起了阿拉巴马人的恐慌;他们中的许多人感到困惑和担忧,开始致电 NHC 伯明翰办公室,迫使其在推特上更正:“阿拉巴马州不会看到#Dorian 的任何影响。我们重复,阿拉巴马州不会感受到飓风多利安的影响。该系统将继续向东走太远。” 在推文中提到阿拉巴马州肯定是一个错误。在某个时候,飓风中心的位置总是有 30% 的可能性最终会超出 NHC 的不确定性范围,但是在 9 月 1 日上午,多里安袭击阿拉巴马州的可能性“比预期的要大”。天可以忽略不计。锥体的最西端边界离阿拉巴马州的东南端很远。即便如此,特朗普总统仍拒绝作出更正或道歉。相反,他反复加倍。在 9 月 4 日的白宫简报中,他试图证明存在数字对象标识符 10.1109/MCG.2019.2961716 在某个时候,飓风中心的位置总是有 30% 的可能性最终会超出 NHC 的不确定性范围,但是在 9 月 1 日上午,多里安袭击阿拉巴马州的可能性“比预期的要大”。天可以忽略不计。锥体的最西端边界离阿拉巴马州的东南端很远。即便如此,特朗普总统仍拒绝作出更正或道歉。相反,他反复加倍。在 9 月 4 日的白宫简报中,他试图证明存在数字对象标识符 10.1109/MCG.2019.2961716 在某个时候,飓风中心的位置总是有 30% 的可能性最终会超出 NHC 的不确定性范围,但是在 9 月 1 日上午,多里安袭击阿拉巴马州的可能性“比预期的要大”。天可以忽略不计。锥体的最西端边界离阿拉巴马州的东南端很远。即便如此,特朗普总统仍拒绝作出更正或道歉。相反,他反复加倍。在 9 月 4 日的白宫简报中,他试图证明存在数字对象标识符 10.1109/MCG.2019.2961716 锥体的最西端边界离阿拉巴马州的东南端很远。即便如此,特朗普总统仍拒绝作出更正或道歉。相反,他反复加倍。在 9 月 4 日的白宫简报中,他试图证明存在数字对象标识符 10.1109/MCG.2019.2961716 锥体的最西端边界离阿拉巴马州的东南端很远。即便如此,特朗普总统仍拒绝作出更正或道歉。相反,他反复加倍。在 9 月 4 日的白宫简报中,他试图证明存在数字对象标识符 10.1109/MCG.2019.2961716
