Abstract The 3-km Norwegian Reanalysis (NORA3) is a 15-yr mesoscale-permitting atmospheric hindcast of the North Sea, and Barents Sea. With horizontal resolution 3 km, nonhydrostatic numerical weather prediction model HARMONIE–AROME runs explicitly resolved deep convection yields fields that realistically downscale ERA5 reanalysis. wind field much improved relative to its host analysis, in part...

The evolution of the mesoscale flow and precipitation distribution are investigated for a small mesoscale convective system (MCS) that evolved in a nearly barotropic environment exhibiting moderate instability and weak wind shear. Observations primarily from a single Doppler radar detail the growth of the MCS from the merger of several clusters and lines of vigorous convective cells into a matu...

In a previous work (Hernández-Bernal et al., 2021, https://doi.org/10.1029/2020je006517) we performed an observational analysis of the Arsia Mons Elongated Cloud (AMEC), which stands out due to its impressive size and shape, quick dynamics, fact that it happens during Martian dusty season. Observations show morphology can be split in head, on western slope volcano around 120 km diameter; tail, ...

These last years ground-based astronomy has been looking towards Antarctica, especially its summits and the internal continental plateau where the optical turbulence appears to be confined in a shallow layer close to the icy surface. Preliminary measurements have so far indicated pretty good value for the seeing above 30-35 m: 0.36” (Agabi et al. 2006), 0.27” (Lawrence et al. 2004) and 0.3” (Tr...

Stream mesoscale habitats have systematic topographic relationships to hyporheic flow patterns, which may create predictable temperature variation between mesoscale habitat types. We investigated whether systematic differences in temperature metrics occurred between mesoscale habitats within reaches of small streams tributary to the upper Little Tennessee River, southern Appalachians. Surface w...
