Science Use Cases Example 4: Relative Humidity at 700 hPa

Services Used: 3D variable 2D slice

Datasets used: ECMWF-Interim Relative Humidity

Scientific Merit: This variable most clearly shows the low cloud regions, as the Relative Humidity (RH) is very low above the boundary layer, whose top is generally well below this pressure level. The Intertropical Convergence Zone (ITCZ) and South Pacific Convergence Zone (SPCZ) are also well-represented as having mean RH at 700 hPa around 60-70% (or higher); Same Time Period of Previous slide, and domain: Lon:[0,360],Lat:[-60,60]
