美国物候探索：蝉与地温

NOAA最新公布一条新闻，大意是说今年启动一个公众科学项目：蝉与地温，欢迎公众加入测地温的网络和报告发现。

有劳英文较好的会员简略翻译一下。

我2007年创立应用气象版块，至今6年，应气对我国公众来说，依然处于超前的位置，连物候都是，甚至跟健康息息相关的家居风水，依然大多数人以为只是迷信，建议应该重视。

NCDC’s Data Help Track the Emergence of Periodical Cicadas

In spring 2013, the return of the 17-year cicadas will cover areas from Georgia to Connecticut, and the air will hum with their mating buzz. These bugs with their black bodies, striking red eyes, and orange wing veins have a rather unique lifespan. The periodical cicadas returning this year, known as the Magicicada Brood II, have been living   underground for the past 17 years.


It is believed that the particular night of the periodical cicadas’ emergence depends on soil temperature. Cicada juveniles, or nymphs, emerge when the soil temperature at 8 inches in depth exceeds approximately 64°F. In order to predict the cicadas’ arrival this year, the National Public Radio’s Radiolab developed a citizen-science project, which invites the public to plant a homemade temperature sensor in the ground and report their findings.


To assist in the project, the Radiolab is also employing soil temperatures from NCDC’s U.S. Climate Reference Network (USCRN) in their endeavor. Because scientists placed USCRN instruments in pristine locations with consistent instruments and triplicate measurements, these temperatures provide baseline  observations to help identify potentially unreliable readings and create a more robust record to understand local variability. These official sensors also add additional data points for Radiolab’s map of “swarmaggedon.”


The periodical cicadas are not generally considered pests. However, their long and loud choruses accompanied with their somewhat menacing appearance threatens to crash weddings, graduations, and other outdoor activities during May and June, making predicting their emergence important to planners and to insect enthusiast that wish to see a rare natural wonder.
