Because of the large range of difficulty that exists beyond Class IV, Class V is an open-ended, multiple-level scale designated by class 5.0, 5.1, 5.2, etc. Each of these levels is an order of magnitude more difficult than the last. That is, going from Class 5.0 to Class 5.1 is a similar order of magnitude as increasing from Class IV to Class 5.0.
Lowest astronomical tide (LAT) is defined as the lowest tide level which can be predicted to occur under average meteorological conditions and under any combination of astronomical conditions. [3] Many national charting agencies, including the United Kingdom Hydrographic Office and the Australian Hydrographic Service , [ 4 ] use the LAT to ...
The zero level can be arbitrary, but it is usually close to the bottom of the stream or river or at the average level of standing bodies of water. Stage was traditionally measured visually using a staff gauge, which is a fixed ruler marked in 1/100 and 1/10 foot intervals, [ 3 ] however electronic sensors that transmit real-time information to ...
Level 1 – Basic Principles Observed and Reported Level 2 – Potential Application Validated Level 3 – Proof-of-Concept Demonstrated, Analytically and/or Experimentally Level 4 – Component and/or Breadboard Laboratory Validated Level 5 – Component and/or Breadboard Validated in Simulated or Realspace Environment
The National Weather Service's arrow showing the EF scale. This includes a description word for each level of the scale. The Enhanced Fujita scale (abbreviated as EF-Scale) is a scale that rates tornado intensity based on the severity of the damage they cause.
3) Mobile homes will be heavily damaged or destroyed. 4) Homes and businesses will have substantial roof and window damage. 5) Expect extensive tree damage and power outages. Alternate wording: 1) You are in a life-threatening situation. 2) Flying debris may be deadly to those caught without shelter. 3) Mobile homes will be heavily damaged or ...
The Emergency Severity Index (ESI) is a five-level emergency department triage algorithm, initially developed in 1998 by emergency physicians Richard Wurez and David Eitel. [1] It was previously maintained by the Agency for Healthcare Research and Quality (AHRQ) but is currently maintained by the Emergency Nurses Association (ENA).

Lightning is frequent, 11–15 cloud-to-ground strikes in a 5-minute period. 5 Numerous thunderstorms.
