How Finnish technology helped the Bahamas cope with Hurricane Dorian

当极端天气罢工时，早期警告和警报对于为暴风雨做好准备而言至关重要。得益于Vaisala新实施的气象解决方案，巴哈马可以发出准确的警报，使成千上万的人有机会寻求避难所的多里安。

In late 2016, the Bahamas decided to invest in a new nation-wide meteorology network to improve itsweather forecasting capabilities。在2017年期间，Vaisala开始交付最新的气象技术，提供硬件 - 天气雷达和气象站 - 以及软件以及与芬兰气象学院（FMI）的合作伙伴关系。

As Hurricane Dorian hit the Bahamas in September 2019, Vaisala’s systems were put up to the test. With the help of Vaisala’s solutions, more accurate information and alerts could be sent out, enabling thousands of citizens and organizations to prepare for and seek shelter from the threat of Dorian.

“多利安飓风以最大持续的风速超过180 mph（接近300 km/h）袭击了巴哈马，这是9月在登陆时记录的大西洋飓风的最高风速。风暴对这些岛屿造成了重大破坏。大多数结构被扁平或扫到海中，至少有70,000人无家可归。如果飓风没有得到很好的监控和及时的警报，那么后果可能会更糟。这表明了系统对我们的客户的重要性。”Aleksis Kajava, Head of Latin America, Vaisala.

Improved weather forecasting capabilities of the Bahamas Department of Meteorology, both through advanced instrumentation and increased expertise, will make it possible to provide advance warnings of approaching severe weather – like in the case of Dorian.

After Hurricane Dorian, three Vaisala automatic weather observation systems are still in place and operational. The weather radar tower and the radome have been designed to resist hurricane winds, but Dorian was an extreme Category 5 (highest category) major hurricane with wind speed exceeding the tower and radome specifications in gusts.

该合同包括四个新的天气雷达和五个岛屿上的一次雷达升级，机场的9个自动天气观察系统以及16个自动气象站以及民用工程和安装服务。在过去的2。5年中，迄今为止，Vaisala在达成的九个自动天气观察系统中安装了六个，在巴哈马的五个天气雷达中，已安装了六个。该项目估计将在2020年4月底之前完成。
