World Weather

World Weather Attribution uses weather observations and climate models to understand how climate change influences the intensity and likelihood of extreme weather events. The studies also assess the role of vulnerability and exposure in the extent of the impacts.
Founded in 2015 by Dr. Friederike Otto and Dr. Geert Jan van Oldenborgh, World Weather Attribution (WWA) scientists quantify how climate change influences the intensity and likelihood of an extreme weather event. They often do this using weather data and computer modelling, and often immediately in the aftermath of the extreme event.
To encourage actions that will make communities and countries more resilient to future extreme weather events, WWA studies also evaluate how existing vulnerability worsened the impacts of the extreme weather event.
The WWA initiative was formed in 2015 and has now performed more than 50 attribution studies on heatwaves, extreme rainfall, drought, floods and forest fires around the world. The methods used have been improved over the years and have been published in the peer-reviewed scientific literature together with many of the studies of individual events.
The world weather is an ever-changing and complex phenomenon that plays a significant role in shaping the lives of people and ecosystems across the globe. Weather conditions such as temperature, precipitation, wind, and humidity can have significant impacts on agriculture, transportation, infrastructure, and public health.
Previous record of 58C recorded at El Azizia Libya was reviewed (2010-2012) by a World Meteorological Organization (WMO) Commission of Climatology (CCl) special international panel of meteorological experts conducted an in-depth investigation of the long-held world-record temperature extreme of 58ºC (136.4 ºF). That temperature (often cited by numerous sources as the highest surface temperature for the planet) was recorded at El Azizia (approximately 40 kilometers south-southwest of Tripoli) in what is now modern-day Libya on 13 September 1922.

Editor's note: This article was originally published on May 4, 2023, and has been updated regularly throughout the year to include further extreme weather events around the world. Amid ever-more intense and frequent extreme weather events, it is not intended as an exhaustive list. It does, however, help convey the scale of the impact that the climate emergency is having right now on lives and livelihoods globally.
What's more, things are slated to get worse. In the most recent report released by the Intergovernmental Panel on Climate Change (IPCC), published in March, environmental experts predict that at our current rate of collective inaction against the climate crisis, the world could be facing a 1.5 degrees Celsius temperature rise by the beginning of the 2030s. As such, extreme weather events would increase in frequency and strength.
At least seven weather-related deaths were reported, while several people were injured. Houses and electricity infrastructure were also damaged, leaving 1.2 million people in France and thousands in the UK without power, according to AP News.
Almost 40 million people were put under a winter weather alert across the southern-central United States in late January and early February this year, as a winter storm swept states from Tennessee to Texas.
The disasters included 14 severe weather events (damages done by thunderstorms, hail, and/or tornadoes), six floods, five droughts, three tropical cyclones, and one European windstorm. Comparing the total damages so far in 2022 to past years is difficult, the broker cautioned, because the 2022 losses are expected to be dominated by Hurricane Ian, and it will some months before those can be tallied.
3) Two weather mega-disasters costing over $20 billion have hit Earth in 2022: Hurricane Ian in the U.S., and the European drought and heat wave. There has been a substantial rise in such $20-billion-plus mega-disasters in recent years (Figure 2). This is greatly concerning, as mega-disasters are likely to overwhelm local resources needed to respond and recover, threaten insurers with insolvency, and disrupt global supply chains.

Please explain the \"ensemble\" options on the precipitation forecasts.A. Modern weather forecasts are typically obtained from ensemble forecasting systems.  Take a look at this article to learn about ensemble forecasts: -centre/fact-sheet-ensemble-weather-forecastingWorld Ag Weather obtains the ensemble data and calculates the range of possibilities from the distribution of the ensemble forecasts.  For example, the Ensemble Median is the median precipitation amount from the distribution of forecasts; this means that half of the members show less precipitation, and half show more.  The US and Canadian ensemble systems have 21 members, and the European system has 51 members.The \"high resolution\" forecasts are from the deterministic (single forecast) models that are run at higher spatial and temporal resolution - these forecasts provide more detail and they are usually more accurate, but they contain only one ensemble member. Q. How can I view data for other places in the world?A. Some of our data products are provided only for the map regions listed in the left menu bar.  However, current temperatures, current weather observations, and past max/min temperature reports can be viewed in Google Maps, which allows you to customize the map area and zoom level. Q. Can I zoom in to see greater detail?A. See previous answer.  Only current temperature, current weather conditions, and past max/min temperature reports can be viewed on a customizable map. Q. What is 'UTC' time?A. UTC is Coordinated Universal Time, essentially equivalent to GMT (Greenwich Mean Time).  To convert to your local time, add or subtract hours according to your time zone, including the Daylight Savings adjustment if necessary. Q. What are your data sources?A. Data are obtained from a wide variety of U.S. government and university sources.  For example, the past precipitation data are provided by the Climate Prediction Center; station observations are downloaded and decoded by World Ag Weather; the computer forecasts are disseminated by NCEP and ECMWF.  Contact us for more details. Q. Do you apply quality control to the station observations?A. We apply a limited quality control scheme to remove station reports that appear highly likely to be incorrect.  However, the user is encouraged to check the data with independent sources if reports appear suspect or if accuracy is paramount. Q. What other agricultural analysis products can you offer?A. Check out CropProphet, a quantitative yield forecasting system designed for professionals and institutions who manage crop price risk and make critical market decisions.";if(id==4) window.location.hash="#about";recentHash="#about";document.getElementById('menu1').innerHTML=" ";document.getElementById('menu2').innerHTML=" ";document.getElementById('agdiv').innerHTML='World Ag Weather has been developed as an online weather resource for agricultural interests across the globe.  Our intention is to provide a comprehensive suite of weather information that allows a diverse global audience to monitor the effects of weather on crops.
World Ag Weather was established by Richard James, a meteorologist with experience in both scientific and operational meteorology.  Richard has a background in meteorological research, specializing in the high-resolution modeling of convective storms and in the application of modern meteorological datasets to problems of weather and climate risk management.  He was previously employed as Senior Meteorologist for Storm Exchange and as an independent equities trader.  Richard received his BA degree in natural sciences from Cambridge University in 1999, and his MS and PhD degrees from The Pennsylvania State University in 2001 and 2009.
