Analysis of Observational Characteristics of Extra-Large Hail in Shandong Peninsula on 1 October 2021.

 

Analysis of Observational Characteristics of Extra-Large Hail in Shandong Peninsula on 1 October 2021
Based on observational data, ERA5 hourly reanalysis data, and s-band dual-polarization radar data, the extremely severe convective weather happening in Shandong Peninsula on 1 October 2021 is analyzed. The results show that the process was affected by the upper-level cold vortex, and extremely severe convective weather happened from west to east in the northern area of Shandong Peninsula. Extra-large hail occurred in this process. The upper-level cold vortex provided the synoptic-scale dynamic forcing and unstable thermal stratification conditions, which were conducive to the occurrence of severe convective weather. Read the research paper!

State of the Global Climate 2025.

Image
   The Earth’s climate is more out of balance than at any time in observed history, as greenhouse gas concentrations drive continued warming of the atmosphere and ocean and melting of ice, according to the World Meteorological Organization (WMO) . These rapid and large-scale changes have occurred within a few decades but will have harmful repercussions for hundreds – and potentially thousands – of years. State of the Global Climate 2025 The global climate system is complex. In order to unpack such complexity, the WMO State of the Global Climate 2025 uses Climate Indicators to describe the changing climate. The following site aims to provide an overview of the annually produced State of the Climate report . Please note that for some indicators, 2025 data is not yet available. The latest available data is provided where this is the case. Greenhouse Gases Increasing levels of greenhouse gases, like carbon dioxide, in the atmosphere due to human activities are a major driver of...

Inter- and Intra-Annual Variation of Evapotranspiration in the Data-Sparse Guder River Watershed, Ethiopia.

Image
  Understanding evapotranspiration (ET) variation is crucial for water management and to comprehend the direction of hydroclimatic fluctuations in a changing world. This study aimed to investigate the inter- and intra-annual variation of ET in the data-sparse Guder River watershed using the appropriate ET estimation model. We have evaluated the performance of two widely used remote sensing ETs and three temperature and radiation-based ET models and selected the best-performing data. We have used innovative trend analysis (ITA) and harmonic analysis to find the general trends and periodic variations in ET. The long-term mean ET of the Guder River watershed ranged from 701.7 to 841 mm per year. Over the past two decades, there has been a general declining trend in annual ET. The analysis of seasonal variation showed considerable fluctuations in ET, with the lowest value of 26.7 mm in winter and the highest value of 159 mm in autumn. The seasonal data analysis revealed that the declin...

Now is the time to act. By closing the early warning gap together, we can create a safer, more resilient world.

Image
At the halfway point, we are making strong progress in saving lives, protecting livelihoods, and strengthening resilience across countries and communities. Governments must lead the way Collaboration between the public and private sectors holds significant potential for the Early Warnings for All initiative, with opportunities for engagement across a broad spectrum of private sector actors—both large and small. While government agencies —particularly National Meteorological and Hydrological Services —must remain the source of authoritative warnings, private sector collaboration can help drive innovation, strengthen dissemination, and enhance risk knowledge. From AI-driven forecasting tools to enhanced communication systems , businesses can provide valuable expertise and resources. Whether they are established corporations or local companies, the private sector has a vested interest in leveraging weather and climate information to manage risks, protect assets, optimize operations, ...
