I often receive questions about parameter selection for blocking detection. Here's an example description using potential vorticity from 3-hourly ERA5 data: "We identify blocks as persistent negative potential vorticity (PV) anomalies with the blocking detection method implemented by Steinfeld 2020 (htt...
Our differentiable dynamical core is implemented in JAX, a library for high-performance code in Python that supports automatic differentiation42. The dynamical core solves the hydrostatic primitive equations with moisture, using a horizontal pseudo-spectral discretization and vertical sigma coordinates36,43....
Although this formula predicts intensity, it can be used to forecast SEP occurrence by using a threshold of proton flux (MeV s . The prediction algorithm is evaluated using the false alarm rate and probability of detection, among other metrics, and with different portions of the data depending ...
There were a total of 247 sites over the three years, which are shown on the map in Fig.1. There were two types of sites. The first type were point locations in larger commercial rice fields. These had the location marked with a pole and the coordinates were recorded using a GPS syste...
For ZDR, Towerpy provides different procedures for detecting the system offset using VPs or QVPs of polarimetric variables. The foundation of these procedures lies in the detection of ZDR values that differ from those expected for natural targets, such as light rain or dry snow. First, the zdr...
In stark contrast to satellite imagery, often constrained by resolution limitations that impede swarm detection, DWRs offer unparalleled spatial and temporal resolution, rendering them indispensable tools in this endeavour. Harnessing radar capabilities within the current infrastructure, unleashes unparalleled ...
