    Welcome to the WUWT ENSO (El Niño/La Niña Southern Oscillation) Page. Here you’ll find a collection of the most commonly used graphs, images, and data sources for monitoring ocean temperature and oscillation patterns. These links were submitted by WUWT readers. For ENSO Forecasts, please visit the ENSO Forecast Page. The agricultural value of El Niño-Southern Oscillation(ENSO) phase knowledge has been measured in a value of information framework using economic models. A three stage stochastic U.S. agricultural sector with a global trade model is created to simulate the value of improved ENSO forecast.

    Meanwhile, I have been working on this solar model to improve it. The advanced version is presented here together with new detailed ENSO forecasts. 2. Maximum of solar eruptions in the year sunspot cycle The sunspot maximum of the year cycle is a well known feature. Each group is called a decile – the lowest 10 per cent of historical values is decile 1, the next lowest 10 per cent will be decile 2, and so on, up to the highest 10 per cent of historical values which lie in decile This creates a scale against which we can rank the amount or intensity of a measurement or event.

The value of improved ENSO forecasts: a stochastic bioeconomic model applied to the Pacific Northwest coho salmon fishery Public Deposited.

You do not have access to any existing by: 1. In addition, ENSO forecasting is useful for farmers’ cropping decisions and positively impacts economic surplus.

The findings present that the value of this information is generally positive and. The interdisciplinary study involved the analysis of data and models from meteorology, plant science, and economics under a framework based on Bayesian decision analysis. The estimated annual value of perfect ENSO prediction to U.S.

agriculture is $ by:   The BU of the NMME forecasts is an implementation of Bayes’s theorem, in which the probability distribution of a variable Y (i.e., NMME-based Niño forecasts) is updated when new information (e.g., observation-based Niño) becomes available.

The BU-Model is defined as the method that directly applies BU to the eight models in by: 6. The findings present that the value of this information is generally positive and rises with improved forecast accuracy, with the value of perfect forecasting estimated to be as substantial as CNY million.

However, the value of ENSO forecasting is relatively small in the context of China’s tremendous agricultural by: 1. Randomness in forecast value has significant implications for choices made by forecasters, forecast users and policy makers. To show randomness, we estimate potential economic values of ENSO forecasts for agricultural producers based on two realistic assumptions: the crop prices farmers receive are uncertain; and within an ENSO phase, the Cited by:   To get a flavor for how good or bad the ENSO forecasts have been sincewe compare the average forecasts of the dynamical models (Figure 2) and statistical models (Figure 3) to the observed SST anomalies value of improved ENSO forecasts book the Niño region of the tropical Pacific.

Departures are based on a set of improved homogeneous historical SST analyses (Extended Reconstructed SST –. IRI ENSO Forecast April Quick Look Published: Ap A monthly summary of the status of El Niño, La Niña, and the Southern Oscillation, or ENSO, based on the NINO index (W, 5S-5N).

Use the navigation menu on the right to navigate to the different forecast sections. The ENSO Outlook status is updated each fortnight. The below graph shows the fortnightly values dating back to January The below table shows the monthly value of the ENSO Outlook for historical comparisons.

The ENSO Outlook graph and table are not an official time-line of ENSO events. For the official history of El Niño and La Niña. At the highest price, the value of the forecast ranges from $ in Kansas to $/ac in Oklahoma.

Differences between sites are also noted in the pattern of values over the range of prices. Very similar patterns are observed with the 5P method. At the Washington site. The goal here is to estimate the value of ENSO forecast information to dual-purpose winter wheat production over the U.S.

SHP through simulation. Although Hill et al. () have done similar work, this study will differ from theirs in two by: The study described here represents a preliminary assessment of the value to the entire U.S. agricultural sector of improved ENSO forecasts in the southeastern United States.

This interdisciplinary assessment combines data and models from meteorology, plant sciences, and economics under a value of information framework based on Bayesian. While the Niño index values remained elevated during March, the consensus of forecasters expects these values to decrease between the spring and summer.

In summary, ENSO-neutral is favored for the Northern Hemisphere summer (~60% chance), remaining the most likely outcome through autumn (click CPC/IRI consensus forecast for the chance.

50 accounts for the lower prediction skill of model forecasts issued in these months (Torrence and Webster, ). 51 Thus, advances in the understanding of the dynamical mechanisms involved in the initiation of El Nino~ and 52 the transition to La Nina,~ as well as the introduction of new and improved ENSO prediction models remain 53 necessary.

to provide probabilistic seasonal ENSO forecasts from the ENSO community; 2. to assess whether a multi-expert-ensemble forecast can help to improve ENSO forecasting skill compared to conventional forecasting approaches; 3. to assess how well we understand the processes leading to the evolution of El Niño or La Niña events.

The mere existence of a technical innovation such as improved climate forecasts does not ensure its use (Schultz ), and forecast use has indeed advanced slowly (Trenberth ; Changnon and Kunkel ; Goddard et al.

They concluded that the skill of the Markov models.forecast to the individual’s performance contracts to focus resources to work in the same direction and drive the right behaviours across the business.

This leads to less sandbagging and gaming. • Improved forecast accuracy and reliability: allows focus and intervention on .Recent values of the upper-ocean heat anomalies (near zero) and thermocline slope index (near zero) reflect ENSO-neutral conditions.
