Evolution of the NASA Multi-Scale Ultra-High Resolution (MUR) sea surface temperature (SST) response to the 2018 Atlantic hurricane season. It is common to observe trails of cooler water, or cold wakes, along hurricane tracks as a result of wind-induced mixing and turbulence that brings cold waters at depth to the surface. The cold wakes associated with the 2018 Atlantic tropical cyclones are clearly observed as waters approximately 2°C cooler from normal that persisted for several days. (MUR SST DOI: 10.5067/GHGMR-4FJ04).

Evolution of the NASA Soil Moisture Active Passive (SMAP) sea surface salinity (SSS) response to the 2018 Atlantic hurricane season. It is common to observe patches of 1) salinity freshening due to enhanced precipitation and 2) salinity increase due to wind stress-generated vertical mixing, wherein increased salinity from a mid-level maximum is brought to the surface. The two effects are clearly observed along the tracks of the 2018 Atlantic tropical cyclones. (SMAP SSS DOI: 10.5067/SMP42-3TPCS).
