The first iPhone and iPad build since 10, and the third for Mac. iOS testers get the Mac builds’ work along with this one’s; Mac testers saw some of what follows a build earlier, in 12.
Parameters
Sondex now computes its parameters from the profile, in five groups:
- Thermo. SB, ML and MU CAPE and CIN, DCAPE, 0–3 km CAPE, NCAPE, LCL, LFC, EL, LI, K index, Total Totals, Showalter, and lapse rates for sfc–3 km, 3–6 km, 850–500 mb and 700–500 mb.
- Kinematics. 0–1, 0–3, 0–6 and 0–8 km shear, effective shear, 0–1 km, 0–3 km and effective SRH, BRN and critical angle.
- Composites. SCP, STP (effective and fixed layer), SHIP, significant hail, significant severe, EHI, SWEAT, WNDG, ESP and MMP.
- Motion. Bunkers right and left movers, 0–6 km mean wind, Corfidi downshear and upshear, and 4–6 km storm-relative wind.
- Moisture. PW, mid- and low-level RH, mean mixing ratio, wet-bulb zero, freezing level and convective temperature.
The mixed-layer parcel averages the lowest 100 mb, and the most-unstable parcel is the highest θe in the lowest 300 mb. The effective inflow layer is where CAPE ≥ 100 J/kg and CIN ≥ −250 J/kg.
Charts
- On iPhone the chart fills the screen, with the tab bar hidden and a share button.
- A readout strip under each chart shows the six parameters that matter for it.
- A bottom panel carries the valid time and a scrubber, and times read as valid times instead of forecast hours.
- On iPad at 900 pt and wider, an inspector beside the chart shows the surface readout, the parameters and the layer toggles.
- The Skew-T temperature axis has presets: NWS Standard, Wide, Narrow, Tropical, Arctic and Custom. The default runs from −30 to 50 °C.
- Scrubbing is faster: parcel and hodograph data are cached and computed in the background.
Navigation and setup
- The tabs are Library, Stations, Charts and Search. Settings moved to the gear in the Library header.
- The Library lists favorite and auto-fetch stations even before they have runs.
- First launch asks for your stations, starting with those within 400 km, and the models to fetch. Those models become the auto-fetch default for new stations.
- Settings has an iCloud Sync section with its status and a Sync Now button. Duplicate runs are merged.
Fixed
- SRH. Each layer’s contribution was weighted by its depth over 3 km, which understated SRH badly. It’s now the plain storm-relative sum.
- SWEAT. Negative terms are set to zero, as the index defines.
- CAPE and CIN shading follow where the parcel is warmer or colder than the environment.
- Time-height in pressure coordinates drew 1000 mb at the top. It’s at the bottom now.
- LFC and EL no longer show the −9999 missing value.
- The floating time label is readable in dark mode.
Removed
- The raw BUFKIT text viewer.
- The Library’s Overview, Model Desk and Station Feed tabs and their widgets.
