Visa to pull in the American meteorological society (AMS), according to data released at the annual meeting in Florida per square mile of lightning most times, total number of Texas lightning most.

Visa,Today issued in 2018Annual flash report.This year, according to data compared with the average over the past 10 years, the United States in 2018 the number of lightning falling nearly 2 million times.Visa,利用其国家雷电监测网（NLDN）汇编了数据并分析了闪电年份，发现2018年有17,804,321个负地闪，这是最常见的云地闪电。这标志着闪电次数在过去10年间列倒数第三，并且相比美国从2009年至2018年间的19,728,634次闪电均值减少了约190万次。

The report's findings this week at the annual meeting of the American meteorological society in phoenix.

Visa to pull of lightning research scientist Ryan Said Said: "the biggest reason for reducing the number of very simple, that is the number of big storm.""Specifically, the central plains region in spring and summer of 2018 and the central and western regions of air mass contrast strongly, cause the bad weather."

Visa of national lightning monitoring network with specific monitoring ability, can detect the local community, both inside and outside the cloud and cloud lightning impulse, through the national lightning ground monitoring network (NLDN) technology and the national oceanic and atmospheric administration (NOAA) GOES - 16 satellite synchronous data collected from the lightning mapper, detection and cloud lightning events related to the continuous current, this kind of current last longer, more destructive of infrastructure.

Also found that the flash report 2018:

An average of 24 per square mile, Florida negative lightning, is high., Mississippi and Louisiana, Arkansas, Oklahoma, ranked second to the fifth place.
Total number of lightning, Texas, most with 2483805 negative lightning.Florida to 1385710 times a second.In 2018, Oklahoma, Kansas and Nebraska lightning quantity are less than 1 million times.
Harrison county, county, according to data from the lightning Mississippi has the highest average 10 years of lightning, but in 2018, the top 15 counties in Florida in the lightning number 14.

Accurate lightning information and education is very important.According to theThe national oceanic and atmospheric administration (noaa) data, in the past 20 years, 51 times by lightning accidents per year on average in the United States, hundreds of people were injured.In fact, the death toll from over lightning weather events is flooding.

"We found that some of the large area of flash less than usual, including Texas, in 2018 the state's lightning nearly 1 million times less than in 2017," she explains."In addition, Texas, Kansas, Oklahoma and Missouri last spring, the weather is relatively cool, and that means less number of lightning.At the same time, North Dakota, south Dakota and Minnesota's regular storm is bigger, lead to the lightning activity level is higher than the average 10 years."
