List Of Severe Weather Phenomena
Severe weather phenomena are weather conditions that are hazardous to human life and property. Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere. Examples Atmospheric * Fog ** Haar (fog) ** Ice fog Electrical storms * Thunderstorm ** Derecho ** Multicellular thunderstorm ** Pulse storm ** Squall line ** Storm cell (single-cell) ** Supercells, rotating thunderstorms ** Lightning Fire * Wildfire or bushfire (ignition of wildfires is sometimes by lightning strike, especially in "dry thunderstorms") ** Firestorm ** Fire whirl, also called ''firenado'' and ''fire tornado'' Flood * Floods ** Flash flood ** Coastal flooding ** Tidal flooding ** Storm surge Oceans and bodies of water * Harmful algal bloom ** Blue green algae ** Red tide * High seas * Sneaker wave * High tides * King tid ...

Tsunami Warning (Japan)
Japan has a nationwide Tsunami Warning system (). The system usually issues warnings a few minutes after an Earthquake Early Warning (EEW) is issued, should waves be expected, usually when a combination of high magnitude, seaward epicenter and vertical focal mechanism is observed. The tsunami warning was issued within 3 minutes with the most serious rating on its warning scale during the 2011 Tōhoku earthquake and tsunami; it was rated as a "major tsunami", being at least 3 m (9.8 ft) high. An improved system was unveiled on March 7, 2013, following the 2011 disaster to better assess imminent tsunamis. Overview When an earthquake occurs, the Japan Meteorological Agency (JMA) estimates the possibility of tsunami generation from seismic observation data. If disastrous waves are expected in coastal regions, JMA issues a Tsunami Warning/Advisory for each region expected to be affected based on estimated tsunami heights. JMA also issues information on tsunami details such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
