2005年12月12日 · MJO Task Force Dynamical Model MJO Forecasts; The U.S. CLIVAR program instituted a MJO working group to study and develop diagnostics and metrics related to various components related to the MJO during 2006.

A Hovmöller diagram of the 5-day running mean of outgoing longwave radiation showing the MJO. Time increases from top to bottom in the figure, so contours that are oriented from upper-left to lower-right represent movement from west to east.

2014年12月31日 · The surface and upper-atmosphere structure of the MJO for a period when the enhanced convective phase (thunderstorm cloud) is centered across the Indian Ocean and the suppressed convective phase is centered over the west-central Pacific Ocean.

MJO Indices. Daily Timeseries | Composite Maps | Animations | ASCII EOF's | Other MJO Indices and Information. PSL is creating a set of MJO timeseries that quantify current and historic MJO activity. The links and descriptions are below as well as links to some other MJO timeseries created at other institutions.

Outgoing Longwave Radiation (OLR) Anomalies Green shades: Anomalous convection (wetness) Brown shades: Anomalous subsidence (dryness) •MJO activity resulted in negative OLR anomalies across the Indian Ocean, and an enhanced low frequency convective signal extending through the Maritime Continent and southwestern Pacific.

Once SST anomalies associated with an ENSO are in place, the MJO life cycle is influenced by the SST anomalies. When or if an MJO develops, the simplest effect during El Nino is a farther eastward movement of the convection into the central Pacific whereas during La Nina the convection anomalies barely get into the western Pacific.

2022年9月9日 · "The Madden–Julian oscillation (MJO) is the largest element of the intraseasonal (30–90 days) variability in the tropical atmosphere. It is a large-scale coupling between atmospheric circulation and tropical deep convection.[1][2] Rather than being a standing pattern (like ENSO) it is a traveling pattern, propagating eastwards at approximately 4 to 8 m/s, …

2023年12月7日 · Understanding the physical mechanisms of the Madden-Julian Oscillation (MJO) and its evolution is a major concern within the climate community. Its main importance relies on its ability to act as ...

The Madden-Julian Oscillation (MJO), first discovered by Madden and Julian in 1971, is a prominent tropical phenomenon with a typical period of 30–60 days and featured by a large-scale envelope of cloud clusters and rain systems moving eastward along the equator.

2023年12月20日 · The Madden–Julian Oscillation (MJO), a large storm system over the Indian Ocean and Western Pacific, plays a crucial role in our ability to forecast Earth’s weather 2–4 weeks in advance. Now ...
