Tropical Tracker: Quiet stretch coming before Atlantic comes alive
This was able to factor in enough to take the out-to-sea track highlighted in last weeks Tropical Tracker. Thankfully, while the Atlantic has been cranking out tons of named storms this year, the Atlantic has a whole has had trouble supporting them. The Madden-Julian Oscillation can enhance or suppress tropical development as the disturbance moves around the world. When the Atlantic is under the influence of downward motion or sinking air, tropical development becomes less likely. When the convective or enhanced phase of the MJO sneaks into the Atlantic Basin, tropical development can become more likely.
