The CFS model is different to any other operational weather forecasting model you will see on WeatherOnline. The systems works by taking reanalysis data (NCEP Reanalysis 2) and ocean conditions from GODAS (Global Ocean data Assimilation). Both of these data sets are for the previous day, and so you should be aware that before initialisation the data is already one day old. Caution should be. Highlight: La Nina forecasts popping-up. Fig. 1-2: The NCEP CFS V2 Nino34 SSTA forecast indicates La Nina developing by AUG/SEP/OCT 2020.The GFDL also projects weak La Nina by MAY/JUN/JUL 2020. Discussion: In a bit of a surprise some global forecast models are indicating risk of weak La Nina developing during or just-after mid-2020. The NCEP CFS V2 forecast indicates La Nina-like Nino34 SSTA.

The NCEP Climate Forecast System Version 2 (CFSv2) The CFS version 2 was developed at the Environmental Modeling Center at NCEP. It is a fully coupled model representing the interaction between the Earth's atmosphere, oceans, land and seaice. It became operational at NCEP in March 2011.

CFS V2 also forecasts La Nina to persist through this year. La Nina turns weaker into spring and then strengthens again during summer. ECMWF ensemble plume forecasts La Nina to return to ENSO neutral by summer 2021. JAMSTEC also forecasts a more traditional return to ENSO neutral during spring and summer 2021. UKMO GloSea5 shows La Nina weakening into spring with ENSO neutral likely by summer. After predicting La Nina would drop to super-Nina levels it's now backed off and is forecasting a weak to borderline moderate La Nina as GWV expected.Weather..

The CFS forecast has not just changed longer term, but also changed quite a lot shorter term, suggesting a solid drop in nino 3.4 even for February, with a general cooling trend going forward, in contrast to previous forecasts showing the normal steady warming trend expected for a La Nina event early in a new year. A look at CFS forecast maps shows strong trade activity predicted a fair way. CFS FORECAST As a counterbalance to the Euro models, we mainly use the CFSv2 (Climate Forecast System) LA NINA AND SPRING TORNADOES As history shows, the cold ocean waters in the tropical Pacific can also have a profound influence on the Spring tornado season in the United States.

El Niño and La Niña Contacts, for more information: Andrew Wittenberg Related Areas of Research: Climate Variability and Prediction The El Niño / Southern Oscillation (ENSO) is the Earth's dominant mode of climate variability on seasonal to interannual time scales This strong El Nino would then likely continue on into the winter of 2014-2015. However, because the CFS model is notorious for forecasting an El Nino that never comes true, I'm not buying this forecast. While I do believe we see an El Nino event by this summer 2014, I don't believe it will be a strong El Nino CFS forecast a record strength la nina for this summer and we were medium at best. I don't trust the CFS very far at all at the moment. EC basically suggests neutral with a slight bias towards cool ENSO conditions, and borderline la nina or borderline el nino both possible.

Kingarabian S2K Supporter Posts: 12700 Joined. Furthermore, because the CFS's original forecasts in 1997/98 are already very good (AC > 0.5 at 8-month lead time), the further improvement of the seasonal forecast skill by including the full-strength global warming signal suggests that both the 1997/98 El Niño event and the anthropogenic GHGs together contribute to the record-breaking global warmth in 1998. In contrast, the record.

February 28, 2021 March is expected to be slow in the severe weather department, but it is likely to be the calm before the storm as Severe Weather is expected to ramp up in April and early May... Looking ahead into the month of March, a brief cooldown will affect the eastern 1/3 of the United States early in the month before a slightly warmer than normal regime. When the MJO convection is located initially over the Maritime Continent during the northern summer, the CFS forecast skill is as small as the persistence forecast, whereas HYBRID1 demonstrates the greatest skill improvement. During ENSO winters, the forecast skill is enhanced by ∼30% by HYBRID1. In particular, the skill improvement in La Niña years is noticeably greater than in El Niño. For example, the CFS forecasts for June of a given year are initiated from the first 10 initial conditions in May of that particular year.

Originally there was a lot of talk (last spring) of the potential for a Super El Nino, The National Weather Service Climate Forecast System (CFS) model is now going for an entirely marginal event, barely reaching the .5C criterion. And the official probabilities for El Nino are now only about 65%. So we should not expect much more than a marginal El Nino during the upcoming fall and early.

Winter forecast experiments have been carried out for 10 chosen years. For each year an ensemble of 10 CFS members is executed, whose initial starting dates are from November 29 to December 3 and from December 19 to December 23.

We now know what La Nina is, and how it impacts the jet stream. Now we will take a look at the global long-range models, and how they see the developing La Nina Winter. We decided to focus on the 3 main (or most used) seasonal models. The ECMWF and UKMO from Europe, and the CFSv2 from the United States. Graphics are from the Copernicus Climate EU project.

A Multi-Model Ensemble (MME) based seasonal rainfall forecast customization tool called FOCUS was developed for Myanmar in order to provide improved seasonal rainfall forecast to the country. The tool was developed using hindcast data from 7 Global Climate Models (GCMs) and observed rainfall data from 49 meteorological surface observatories for the period of 1982 to 2011 from the Department of. Analysis tools for tracking and forecasting tropical weathe CFS V2 is still forecasting moderate El Nino conditions to be in place by November but looks unlikely based on the current SST's. In the northern Pacific sea-surface-temperature anomalies are warmer than normal close to Alaska and Canada. In the Atlantic we have quite an unusual SST profile with colder than average SST's to the south-east of Greenland, but warmer than normal towards New. 3 La Nina warm winters all had higher AD values than that in colder La Nina winters. So following weak SH and warm winter; The AD in 2020 is very low with -2.0, with considering less Arctic sea ice+La Niña ,which are favorable to a colder winter. And warmer winter occurrence can be excluded. 2000 2008 1998 Bingyi Wu et al. 2016 AD-blue lin CFS as a Prediction System and Research Tool equatorial southeasterly trade winds are too weak. In the CMIP2 integration with a new version of CFS at T126L64, Indian Ocean errors are reduced but.

National Weather Service backtracking some on El Nino forecast. Via NOAA: After several months of intensification, warmer than normal sea surface temperatures in the Pacific, a sign of El Niño. Only theoretical way to get a warm-neutral ENSO/El Nino by JAS, is if there is a substantial WWB near the dateline within the next 60 days. For the past week, the 90 day CFS 850mb wind forecast (which is extremely in-consistent to say the least) has been showing this (substantial WWB) occurring during the first week of April. We can't trust.

Weather information. Popular weather products and services National Weather Service API. National Weather Service's application programming interface information. I can give you one rather easy prediction thanks to El Nino, and this is a forecast that 2015 will be the hottest year on record globally. 2014 is the current record holder, but with all that warm water releasing heat to the atmosphere, this year is likely to beat it. So far this year, the first 6 months are the warmest Jan.-June on record and June was the hottest on record.

Both are initialized with the CFSR (CFS Reanalysis), which is showing an unrealistically cold Atlantic. reply; odds of a step-up in global average temperature Submitted by Larry Kummer on Fri, 2016-03-18 20:16. Has NOAA written anything forecasting the odds that this El Nino will produce a continuing step-up in global temperatures, as did the 1998-99 event (i.e., not just a temporary bump. Followers of Joe D and I on Weatherbell know from the get go that the basis of our fall and winter forecast was for the nina to still be around, but that the CFS is now way overdone and reactionary. The cooling atlantic is not the end of the overall warm amo, but is in line with what started happening in the 1950s, as is the PDO. In 10-15 years, this whole silly climate debate should be over.
