NSSL/CIMMS Storm Electrification Research
• Storm electrification observations– Studies of OK-LMA data– Balloon-borne electric field & microphysics
• Applications for NWS operations– Storm tracking & trends by storm type– Lightning data assimilation– Lightning forecasts
• Lightning physics (initiation & attachment)• Lightning climatology
