Among these hazards are the results of natural processes and atmospheric, hydrological, or oceanographic phenomena such as floods, tropical cyclones, drought, and desertification. Many countries have established an operational hydrometeorological capability to assist with forecasting, warning, and informing the public of these developing hazards.

A natural hazard [18] is a natural phenomenon that might have a negative effect on humans and other animals, or the environment. Natural hazard events can be classified into two broad categories: geophysical and biological. [19] Natural hazards can be provoked or affected by anthropogenic processes, e.g. land-use change, drainage and ...
This category is a loose grouping of natural hazards caused by the weather. These are here distinguished from Category:Geological hazards and other natural hazards: Category:Natural hazards . Subcategories
Meso-alpha (meso-α) – 200–2000 km scale of phenomena like fronts, squall lines, mesoscale convective systems (MCS), tropical cyclones at the smaller edge of synoptic scale. [6] Meso-beta (meso-β) – 20–200 km scale of phenomena like mesocyclones, sea breezes, and lake effect snow storms. [6] Mesocale often refers to meso-β scale ...
Severe weather is any dangerous meteorological phenomenon with the potential to cause damage, serious social disruption, or loss of human life. [1] [2] [3] These vary depending on the latitude, altitude, topography, and atmospheric conditions.
Nitric oxide present during thunderstorm phenomena, [59] caused by the oxidation of atmospheric nitrogen, can result in the production of acid rain, if nitric oxide forms compounds with the water molecules in precipitation, thus creating acid rain. Acid rain can damage infrastructures containing calcite or certain other solid chemical compounds.
The National Centre for Hydro-Meteorological Forecasting (NCHMF, Vietnamese: Trung tâm Dự báo Khí tượng Thủy văn Quốc gia) is the central and national-level meteorological and weather forecasting service of Vietnam.
