Harvey arose from a tropical wave west of West Africa on 13 August 2017 and quickly travelled westwards across the tropical Atlantic Ocean. Before entering the Caribbean Sea, Harvey was classified as a tropical storm for the first time on 17 August 2017.

The ability of very high frequency (VHF) (∼50 MHz) windprofilers to measure backscatter, winds and turbulence in the troposphere and the lower stratosphere gives them a unique perspective not available with many other remote sounding radar techniques. This capability has been utilized to study the environment of 31 tornadoes generated in the provinces of Ontario and Quebec in Canada over an 11-year period. Tornadoes were mostly of Enhanced Fujita (EF) types EF0 to EF2, with one being EF3. Focus is on events which produced visible damage.

Too little rain, or too much, is often a driver of poverty and hunger, leading to poor nutrition and food insecurity among vulnerable populations.

Australia's Bureau of Meteorology has issued an alert for a La Nina weather event starting next month, saying the chance it would take place was triple the normal likelihood.

The National Drought Management Authority has warned of a possible La Niña between October and December.

TOKYO (Reuters) - Japan’s weather bureau projected on Monday that there are no active El Niño or La Niña patterns now and that it sees a 60 percent chance of normal weather conditions continuing th

The operational medium-range weather forecasting based on numerical weather prediction (NWP) models are complemented by the forecast products based on ensemble prediction systems (EPSs). This change has been recognised as an essentially useful tool for medium-range forecasting and is now finding its place in forecasting the extreme events. Here we investigate extreme events (heatwaves) using a high-resolution NWP model and its ensemble models in union with the classical statistical scores to serve verification purposes.

(Reuters) - A low pressure system about 800 miles east of the Lesser Antilles has a 40 percent chance of strengthening into a tropical cyclone, the U.S.

The Nigerian Meteorological Agency (NiMet) has signed a Memorandum of Understanding (MoU) with Trans-African Hydro-Meteorological Observatory (TAHMO) in The Netherlands, to develop a network of Aut
