厄尔尼诺/拉尼娜年

Adiligirl

       最近在研究厄尔尼诺和拉尼娜，需要判断某年份是El Nino 还是La Nina，由于本科非气象，研究起来一头雾水，主要这些事件判断的标准多，几乎所有事件都是跨年的，可能某年JJA之前是一个EL Nino的衰退，JJA之后又是一个La Nina的发展，各种官方给的数据也不尽相同，算指数所研究的区域也不太一样，有些对EP型和CP型或者是混合型给出的标注也不太相同，总之比较混乱。现在把找到的资料汇总一下，做个记录慢慢摸索吧。

---加图片好麻烦就不贴了---
The Oceanic Niño Index (ONI) has become the de-facto standard that NOAA uses for identifying El Niño (warm) and La Niña (cool) events in the tropical Pacific.  It is the running 3-month mean SST anomaly for the Niño 3.4 region (i.e., 5oN-5oS, 120o-170oW).  Events are defined as 5 consecutive overlapping 3-month periods at or above the +0.5o anomaly for warm (El Niño) events and at or below the -0.5 anomaly for cold (La Niña) events.  The threshold is further broken down into Weak (with a 0.5 to 0.9 SST anomaly), Moderate (1.0 to 1.4), Strong (1.5 to 1.9) and Very Strong (≥ 2.0) events.  For the purpose of this report for an event to be categorized as weak, moderate, strong or very strong it must have equaled or exceeded the threshold for at least 3 consecutive overlapping 3-month periods.

DESCRIPTION: Warm (red) and cold (blue) periods based on a threshold of +/- 0.5oC for the Oceanic Niño Index (ONI) [3 month running mean of ERSST.v5 SST anomalies in the Niño 3.4 region (5oN-5oS, 120o-170oW)], based on centered 30-year base periods updated every 5 years.

Past Events
What years are ENSO years?
Because ENSO events differ in their strength, coverage, and seasonality, there isn't unanimous agreement on what constitutes and ENSO event. But, there are broad agreements and you can find some of the lists researchers have used along with how they chose those years. The list in the right column represents ENSO years based on PSD's Extended Multivariate ENSO Index (MEI.ext).

谢谢，学习了！

哦对了还有这个，厄尔尼诺国家标准。

是的，这个我也搜索到了，但是和这个新指数有些许不同，不知道应该怎样区分。

你好，我想请教一下这张厄尔尼诺国家标准是在哪里找到的呢，这张图片下载下来有些模糊，方便把网址告诉我一下么？谢谢

之前气象家园就有帖子讲这个啊，发个邮件给我（793209554@qq.com），我把文件发给你？
