Ethiopia National Meteorology Agency (NMA) has been serving as the nation's authoritative source of providing weather forecasts for the public, marine, and aviation and the like. When conditions warrant, it also issues warnings.
But, some have doubt about the reliability of its meteorological information. So how credible is the agency's weather forecasting?

A new Malaysian lightning detection network brings benefits for public weather forecasting, worker safety and commercial operations impacted by lightning events. Lightning is one of the most dangerous and frequently encountered weather hazards In Malaysia. It takes lives, causes severe injuries, damages vital infrastructure and disrupts operations.
Professor Ir Dr Mohd Zainal Abidin Ab Kadir, a Director of the Centre for Electromagnetic and Lightning Protection Research at the Universiti Putra Malaysia, says that many Malaysians are not aware their country has the ‘third-highest lightning activity’ in the world.
The US National Lightning Safety Institute says Malaysia experiences an average of 180 to 260 thunderstorm days each year, while the Centre for Electromagnetic & Lightning Protection (CELP) says lightning killed 112 and injured 156 people in Malaysia between 2008 and early 2017.
Every year lightning presents risks to workers and public safety, as well as disrupting the operations of:
Lightning strikes are also a major cause of fallen power lines and trees, wildfires and tyre explosions on earth-moving machinery. Prompt access to real-time lightning and thunderstorm data is intrinsic to improving both meteorological forecasting and prompt safety alerting. The aim is to minimise loss of lives and livelihoods and mitigate other disruption from electrical storms.
Malaysia is estimated to lose about RM250 million each year in infrastructure damages & business disruptions due to electrical outages from lightning strikes.
The Malaysian high-resolution lightning detection network
MetraWeather Asia and TOA Systems, Inc, with the support of Malaysian partner Riajati Sdn Bhd, are currently installing a new high-resolution lightning detection network. The network will integrate more than 19 state-of-the-art TOA lighting detection sensors to provide extensive coverage across both East and West Malaysia.
Bryan Lim, Sales Delivery Manager-Asia for MetraWeather says cloud-to-ground (CG) lightning strikes are extremely dangerous to the safety of collocated teams working outdoors, workers on airport aprons and people congregating for events in places such as public parks and university campuses.
“Detection of the more common but much lower energy intra-cloud (IC) and/or cloud-to-cloud (CC) lightning is also crucial in providing advanced alerting about potential risks.”
“Real-time detection of IC/CC lightning, when combined with other sources of meteorological data such as satellite imagery, rain radar and numerical modelling, can help forecasters to better understand and accurately categorize events,” says Mr Lim.
“TOA and MetraWeather have extensive experience all around the world in both lightning detection and weather safety. We believe that the high level of detection efficiency and location accuracy enabled by this new network, plus the amount of highly accurate data available for each lightning event, will bring substantial benefits to Malaysian public forecasting, worker safety and commercial operations impacted by lightning events.”
With new funds provided by the Government of Canada, WMO and its partners are stepping up efforts to support disaster risk reduction in Small Island Developing States (SIDS) and Southeast Asia.
Environment and Climate Change Canada (ECCC) has allocated CAD 10 million (US$ 7.5 million) to the project entitled “Building Resilience to High-Impact Hydro-meteorological Events through Strengthening Multi-Hazard Early Warning Systems in SIDS and South East Asia. The grant represents Canada`s institutional support to the Climate Risk and Early Warning Systems (CREWS) initiative.
The first meeting of the Project Steering Committee for the Southeast Asia component took place at the National Hydro-Meteorological Service (NHMS) of Viet Nam in Ha Noi on 23 November 2017.
The Indian Meteorological Department Director General of Meteorology, K.J. Ramesh, proposed a Research Consortium involving all the institutions of Andhra Pradesh focusing on science and technology. He stressed on this while addressing the gathering at the three-day National Seminar, on 'Impact of Climate Change on Extreme Weather Events' and 'the Indian Ocean' that began at AU TLN Saba Hall, in November 2017.
An Australian spring wouldn’t be complete without thunderstorms and a visit to the Australian Bureau of Meteorology’s weather radar website. But a new type of radar technology is aiming to make weather radar even more useful, by helping to identify those storms that are packing hailstones.
Most storms just bring rain, lightning and thunder. But others can produce hazards including destructive flash flooding, winds, large hail, and even the occasional tornado. For these potentially dangerous storms, the Bureau issues severe thunderstorm warnings.
For metropolitan regions, warnings identify severe storm cells and their likely path and hazards. They provide a predictive “nowcast”, such as forecasts up to three hours before impact for suburbs that are in harm’s way.
A new weather satellite is circling the earth. The JPSS-1 satellite, launched this weekend (18 November 2017) will provide a huge array of observational, near real-time, data which will be shared with US national and international partners including the Met Office.
As well as gathering day to day weather data the satellite will monitor a wide range of events such as wildfires, snow cover, sea-surface temperature and aerosol detection, important in air quality monitoring. In addition, the satellite will measure the radiation coming from the earth and atmosphere, vital information for weather forecasting models such as those run by the Met Office.
