Review Article: World Sees Record Heat Waves

By Dr. Shah • July 13, 2023 • Knowledge, Public • heat, record, wave, WMO, world • 2 minutes of reading

The article by Anna Fleck discusses global heatwaves and presents preliminary data from the World Meteorological Organization (WMO) regarding recent temperature records. It highlights that the world has just experienced the hottest week on record (average July 3-9) following the hottest June on record. The article provides examples of temperature records being broken in various regions around the world. In South Asia, an exceptional heatwave occurred in April and May 2023, resulting in national temperature records being broken in Thailand, Vietnam, and Laos. Australia and Uruguay also matched their national temperature records last year, while the UK saw its all-time […]

Understanding Heat Waves: A Growing Threat and Path to Solutions

By Dr. Shah • June 7, 2023 • Research, Teaching • heat, wave • 4 minutes of reading

By Shahabuddin Amerudin Heat waves, extreme climate events characterized by prolonged periods of high temperatures, are posing an increasing threat to our society and the environment. Their frequency, intensity, and duration are expected to rise throughout the 21st century. In this article, we will explore the key insights from recent research on heat waves, their impact on society and the environment, and propose short and long-term solutions to address this pressing issue. Understanding Heat Waves Heat waves occur when temperatures soar well above the normal values for a specific region. While they can happen at any time of the year,

This figure provides a simple cross-sectional illustration of the kind of issues that arise. We wish to determine the distance separating points A and B. If A and B are not too far apart (e.g. less than 10 km) we could use a high precision laser rangefinder to establish the slope distance between A and B, assuming there is no atmospheric distortion. In practice, there will be some distortion and the laser wave path will need to be adjusted in order to provide an estimated slope path distance. This, in turn, will require further adjustment if it is to be referenced
