# [−][src]Crate sounding_analysis

Functions and data types for analyzing soundings from the sounding-base crate.

## Purpose

Provides analysis capabilities for the sounding-base crate.

## Structs

Analysis | Convenient package for commonly requested analysis values. |

Layer | A layer in the atmosphere described by the values at the top and bottom. |

Parcel | Variables defining a parcel as used in parcel analysis. |

ParcelAnalysis | Parcel analysis, this is a way to package the analysis of a parcel. |

ParcelProfile | Hold profiles for a parcel and it's environment. |

PlumePotentialAnal | An analysis of the potential energy of a convective plume vs. a representative starting temperature. |

## Enums

AnalysisError | Error type for the crate. |

## Functions

bunkers_storm_motion | Calculate the super cell storm motion using the "id" method. |

cold_surface_temperature_layer | Assuming a warm layer aloft given by |

convective_parcel | Get the convective parcel - this is the surface parcel that will rise without any lifting. |

convective_parcel_initiation_energetics | Analyze the sounding to get the values of (t˳, Δt˳, E˳, ΔE). |

dcape | Downdraft CAPE. |

dendritic_snow_zone | Find the dendtritic growth zones throughout the profile. It is unusual, but possible there is more than one. |

effective_inflow_layer | Get the effective inflow layer. |

equivalent_potential_temperature | Given a sounding, calculate a profile of the equivalent potential temperature. |

freezing_levels | Find the freezing/melting levels below 500 hPa. |

hail_growth_zone | Find the hail growth zones throughout the profile. It is very unusual, but possible there is more than one. |

haines | The Haines index for fire weather. |

haines_high | The high level version of the Haines index for fire weather. |

haines_low | The low level version of the Haines index for fire weather. |

haines_mid | The mid level version of the Haines index for fire weather. |

hot_dry_windy | The Hot-Dry-Windy index |

hydrolapse | Get the hydrolapse in (kg/kg)/km |

inversions | Get all inversion layers up to a specified pressure. |

kindex | The K-index |

layer_agl | Get a layer that has a certain thickness, like 3km or 6km. |

lift_parcel | Lift a parcel for a convective parcel analysis. |

linear_interpolate | Interpolate values given two parallel vectors of data and a target value. |

linear_interpolate_sounding | Interpolate values from the vertical sounding using pressure as the primary coordinate. |

lowest_level_parcel | Get the lowest level parcel. This should be the surface parcel, but some files do not have complete information at the surface, so the first level above the ground is best you can do. |

max_temperature_in_layer | Maximum temperature in a layer. |

max_temperature_in_profile | Maximum temperature aloft. |

max_wet_bulb_in_layer | Maximum wet bulb temperature in a layer. |

max_wet_bulb_in_profile | Maximum wet bulb temperature aloft. |

mix_down | Descend a parcel dry adiabatically. |

mixed_layer_parcel | Create a mixed layer parcel. |

most_unstable_parcel | Get the most unstable parcel. |

partition_cape | Partition the CAPE between dry and moist ascent contributions. EXPERIMENTAL. |

potential_temperature | Given a sounding, calculate a profile of the potential temperature. |

precipitable_water | Precipitable water (mm) |

pressure_layer | Get a layer defined by two pressure levels. |

pressure_parcel | Get the parcel at a specific pressure. |

relative_humidity | Given a sounding, calculate a profile of relative humidity. |

relative_humidity_ice | Given a sounding, calculate a profile of relative humidity with respect to ice. |

robust_convective_parcel | A more robust convective parcel analysis. |

sfc_based_inversion | Get a surface based inversion. |

warm_wet_bulb_layer_aloft | Assuming the wet bulb temperature is below freezing at the surface, this will find the warm layers aloft using the wet bulb temperature. Does not look above 500 hPa. |
