weather ready nation
Weather Ready Nation
  • Society is prepared for and responds to weather-dependent events
  • Goal: Improve weather decision services for events that threaten lives and livelihoods
purpose
Purpose
  • Need accurate numerical analysis of fine scale weather phenomena
    • Improve real-time assessment of the current state of the atmosphere
    • Enable NWP for time scales of several hours
    • Improve the short range prediction of all types of high impact weather
  • Local Analysis and Prediction System (LAPS) is a tool to help us reach our goal
laps applications
LAPS Applications
  • Enhancing situational awareness
    • Provides a more detailed assessment of the state of the atmosphere
  • Tool for improving short term forecasts
    • Assist in forecast verification and improve forecaster confidence
  • Improve understanding by NWS staff
short term forecast applications
Short Term Forecast Applications
  • Severe Weather Analysis
    • Highlight convective potential and instability
  • Winter Weather Analysis
    • Real time wind analysis, quickly identify areas of Ageostrophic vertical circulations and frontogenesis
  • Atmospheric Rivers
    • Identify moisture trends, synoptic-forced systems
  • Assist in aviation forecasts, temperature trends, marine weather forecasts
  • Used in GFE to represent the observed conditions (eg., Sfc temp)
    • Diurnal T and Td grids can be generated from this grid for up to six hours
laps anticipation of svr wx
LAPS – Anticipation of SVR WX
  • Used as a real-time situational forecasting tool
  • Highlight real-time severe weather trends
  • Increase forecaster awareness may lead to increase lead time
    • Note: Graphic from 2010 LAPS Conference, Role of LAPS in NWS
