Sea surface temperatures in the storm's trajectory were running 1 to 2 degrees Celsius above average, providing ample heat and moisture to fuel the storm's convection. A strong high-pressure system over the western Atlantic directed the storm on a northwesterly trajectory.
Convection Structure and the Genesis of Hurricane Melissa
Following the protocol of the National Hurricane Center, the system was designated as Tropical Depression Fifteen once this circulation became well-defined. Formation and Initial Organization By the time the wave reached the central Atlantic, satellite imagery indicated a marked improvement in its convective structure.
Steering Currents and Path Once Hurricane Melissa achieved hurricane intensity, its movement was primarily dictated by large-scale steering currents in the mid-latitude atmosphere. Hurricane Melissa formed as a significant weather event in the late-season Atlantic basin, developing from a complex interplay of atmospheric and oceanic forces.
Convection Structure and Environmental Factors Driving Hurricane Melissa's Formation
These factors enabled rapid strengthening, leading to the storm's upgrade to hurricane status just days after its initial formation. Understanding the genesis of Hurricane Melissa requires examining the specific environmental conditions that allowed a disorganized cluster of thunderstorms to consolidate into a rotating cyclone with sustained winds reaching hurricane status.
