Struct StormRelativeVelocity 

pub struct StormRelativeVelocity { /* private fields */ }

Storm-relative velocity — subtracts a storm motion vector from radial velocity.

This makes it easier to identify rotation signatures (mesocyclones) in storm systems by removing the bulk storm motion. The input field should contain radial velocity data.

The storm motion is specified as a direction (degrees from north) and speed (m/s). The component of the storm motion along each gate’s radial direction is subtracted from the measured velocity.

Example

use nexrad_process::derived::StormRelativeVelocity;

// Storm moving from 240° at 15 m/s
let srv = StormRelativeVelocity::new(240.0, 15.0)?;
let sr_velocity = srv.process(&velocity_field)?;

Implementations

impl StormRelativeVelocity

pub fn new(storm_direction_degrees: f32, storm_speed_mps: f32) -> Result<Self>

Create a new storm-relative velocity processor.

Parameters

• storm_direction_degrees — Direction the storm is moving FROM, in degrees clockwise from north (0-360).
• storm_speed_mps — Storm movement speed in m/s.

Errors

Returns an error if speed is negative.

Trait Implementations

impl SweepProcessor for StormRelativeVelocity

fn name(&self) -> &str

A human-readable name for this processor.

fn process(&self, input: &SweepField) -> Result<SweepField>

Process the input field, producing a new field with the same geometry.
