目前MJO出现了不连续东传的现象,这主要是因为在热带出现了两个对流区:一个在东南亚到西太平洋一带,另一个在东太平洋。后者与MJO的低频信号的东传相一致。未来两周MJO将抵达非洲,随后进入印度洋。
未来一周,北美西南部和中美洲地区对流活跃,而中印度洋到东印度洋一带则是对流抑制区。南海、东海有热带气旋活跃,但将迅速变性为温带气旋。另外菲律宾以东有较小可能性有热带气旋形成。
第二周,对应MJO对流位相到达非洲地区,西太平洋和南海的热带气旋不活跃。动力学模式对于MJO在印度洋的东传速度和进入海洋性大陆的时间分歧较大。
据CFS,西太平洋下一次热带气旋活跃期要等到7月中旬。

                  Disorganized shower and thunderstorm activity extending from the northwestern Caribbean Sea to the southern Gulf of Mexico is associated with a surface trough. Environmental conditions are not expected to be favorable for significant development. However, heavy rains and gusty winds are likely to spread across the Yucatan Peninsula and the central Gulf of Mexico through Saturday. This activity is likely to reach portions of the Texas and southwestern Louisiana coasts by Sunday. For more details on this system please see products issued by your local weather office and High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent.
