El Niño / La Niña Update
28. maj 2020, WMO, Novice, Voda
Sea surface temperature conditions in the tropical Pacific remain neutral in terms of El Ni?o-Southern Oscillation (ENSO) status, signifying that neither El Ni?o nor La Ni?a is currently prevailing. Recent cooling of the sub-surface waters in the region has subsequently caused the hitherto slightly above-average sea surface temperatures to return to near-average levels during May. The latest seasonal forecasts from the WMO Global Producing Centers of Long Range Forecasts (GPCs-LRF) indicate that tropical Pacific sea surface temperatures are likely to cool further, potentially approaching weak La Ni?a levels during the second half of 2020. Given current conditions and model predictions, the chance of ENSO-neutral conditions continuing through June-August 2020 is estimated to be around 60%, with a 30% chance of La Ni?a. Chances for La Ni?a rise to 40% for the September-November period. National Meteorological and Hydrological Services will closely monitor changes in the state of ENSO over the coming months and provide updated outlooks, taking into account the relatively greater uncertainty in seasonal forecasts at this time of the year.

Climate characteristics and factors behind record-heavy rain in Japan in August 2021 - Japan Meteorological Agency
24.9.2021, WMO
In mid-August 2021, areas from western to eastern Japan experienced record-heavy rain.?The conditions observed are mainly attributed to the following:?- Unusually for mid-summer in eastern and western Japan, like atmospheric flow in the latter half of the early-summer rainy season, known as the Baiu, a stationary front was strengthened by a significant north-south gradient of temperature in the lower troposphere between the Okhotsk High to north of Japan and the southward shifted North Pacific Subtropical High (NPSH) expanding to the south of Japan. A continuous confluence of water...
HydroHub improves hydrological monitoring
6.9.2021, WMO
The Swiss Agency for Development and Cooperation (SDC) has allocated CHF 2.4 million to the WMO Global Hydrometry Support Facility (WMO HydroHub) to fund Phase II, which was?officially launched on 1 September.
?The WMO HydroHub has proven instrumental in increasing the quality and amount of hydrometric data as a global public good decisive to disaster risk reduction, sustainable water management and environmental protection,? stated Simon Zbinden, Head of the Global Programme Water at SDC.
About 60% of WMO Member States and Territories report declining local water monitoring...
Weather-related disasters increase over past 50 years, causing more damage but fewer deaths
31.8.2021, WMO
A disaster related to a weather, climate or water hazard occurred every day on average over the past 50 years ? killing 115 people and causing US$ 202 million in losses daily, according to a comprehensive new report from the World Meteorological Organization (WMO).
The number of disasters has increased by a factor of five over the 50-year period, driven by climate change, more extreme weather and improved reporting. But, thanks to improved early warnings and disaster management, the number of deaths decreased almost three-fold.
According to the WMO Atlas of Mortality and Economic Losses...
Atlas of Mortality and Economic Losses from Weather, Climate and Water Extremes (1970-2019).
31.8.2021, WMO
WMO will release its Atlas of Mortality and Economic Losses from Weather, Climate and Water Extremes (1970-2019) on 1 September 2021.
The Atlas is WMO?s most exhaustive compilation to date of fatalities and economic costs from natural hazards. It provides comprehensive details of recorded disasters and their impacts, both at global and regional level. It gives statistics for the entire 50 year period, as well as a decadal breakdown which shows the evolution of disasters in our changing climate.
The Atlas is a multi-agency collaboration, with contributions from many partners including...
New report shows impacts of climate change and extreme weather in Latin America and Caribbean
17.8.2021, WMO
Climate change and extreme weather are threatening human health and safety, food, water and energy security and the environment in Latin America and the Caribbean. The impacts span the entire region, including Andean peaks, mighty river basins and low-lying islands, according to a new report from the World Meteorological Organization (WMO). It flags concerns about fires and the loss of forests which are a vital carbon sink.
The "State of the Climate in Latin America and the Caribbean 2020" provides a snapshot of the effects of increasing temperatures, changing precipitation patterns,...
