The meaning of urban climate research

 Urban climate research is an interdisciplinary field that studies the interactions between cities and the environment, with a focus on how cities affect, and are affected by, climate and weather patterns. Cities have unique characteristics that can create a microclimate with distinctive features such as higher temperatures, reduced air quality, and more extreme weather events compared to their surrounding rural areas. This difference is often referred to as the urban heat island (UHI) effect. Urban climate research aims to provide insights into the mechanisms that lead to UHIs and its potential impacts on human life, the environment and the economy.

Urban climate research methods typically involve field experiments, observational studies, and computer models. Researchers use a variety of instruments such as high-resolution weather stations, UAVs, lidars, temperature sensors, air quality monitors, and satellite data to measure the variables that affect urban climate, including weather patterns, air quality, vegetation, thermal properties of urban surfaces, and building heights and spacing. These measurements are then analyzed to identify urban climatology patterns and trends.

In addition to local weather observations, urban climate research also takes into account the impact of global climate change on urban areas. Many cities are facing the challenge of adapting to a changing climate, which includes preparing for more frequent and intense heatwaves, droughts, floods, and extreme weather events such as hurricanes and tornadoes. Urban climate research can help identify adaptive measures, such as green infrastructure, cool roofs, and reflective pavements, that can mitigate the urban heat island effect and its impacts on human health, energy consumption, and the environment.

Overall, urban climate research plays a crucial role in helping cities and urban planners understand and adapt to changing weather and climate patterns, and create more sustainable, resilient, and livable urban environments. The research is important as it helps to inform policies, guidelines and design strategies aimed at mitigating the negative effects of urbanization and climate change, and building more resilient cities in the face of future challenges.

Urban climate research is a rapidly developing field that focuses on understanding the dynamics of climate, air quality, and the energy balance in urban areas. The field has a long history, with the first bibliography on urban climate dating back to 1970. Despite this long history, urban climate research still represents a relatively small percentage of all urban studies.

The focus of urban climate research is to understand the complex interactions between urban environments and the climate system, including factors such as land use and cover, building design, air quality, and the effects of climate change. By understanding these interactions, researchers can design strategies to mitigate the negative effects of urbanization on the climate system and improve the resilience of cities to climate change.

Recent research has shown that building shadows in dense urban areas can create localized cool islands during the day.  This is important to consider as urban areas are particularly vulnerable to climate hazards and Urban climate research is a rapidly developing field that focuses on understanding the dynamics of climate, air quality, and the energy balance in urban areas.

How to cool during heatwaves

Under a warming climate intense heatwaves are expected that would stay for hours, days, weeks and months.  It becomes even worse under urbanization - the more cities grow , the  more natural land covers such as vegetation and soil are replaced by impervious surfaces such as concrete, asphalt roads and buildings. These impervious  urban surfaces can't retain water much longer like soil and vegetation and this would exacerbate the heating further.  Urban heat islands add more than 3 deg. C (Fig. 1) to the heatwaves. The combined effects of heatwaves and urban heat islands are heat-related illnesses and death - specifically affecting young toddlers and old people because their body regulation mechanism is lower. Figure 1. Urban heat island adds more than 3 deg. C to the heatwaves and increases the frequency or duration of the heat. Under a warming climate, it is only a matter of time before we start to seek for cooling mechanisms both for short term and long t...

Urbanisation: The problem of local climate modification

People migrate to cities due to different reasons such as easy access to schools, health facilities, jobs and transportation . More people, therefore, live in urban areas than in rural. According to the  United Nations estimate, in 2014 more than 54% of the world population dwell in cities. It was 30% in 1950. Projections indicate that 66%  of the world's population will live in urban by 2050 . Most of urban people reside in relatively small areas with high number of inhabitants per square meter of land (UN, 2015): " Close to half of the world's urban dwellers reside in relatively small settlements of less than 500, 000 inhabitants, while only around one in eight live in the 28 mega-cities with more than 10 million inhabitants. " It is ages since people noticed that urban air was different from rural air. However, it was air pollution which is the hallmark of the urban atmosphere. In 1818 Luke Howard (1772-1864) published the first edition of a book deal...

Are we creating our own weather and climate reality?

Let us explore alternative ideas about the causes of the extremes of weather and climate. Are we creating our own weather reality? According to Quantum Mechanics, "the action of measurement changes the state of a physical system". This is derived from the superposition principle and "the Schrodinger's cat paradox", i.e., a cat put in a box with a radioactive element is both dead and alive until someone opens the box. This is to mean that the state of the cat is the superposition of the two states "death" and "life". Whether the superposition is linear or non-linear doesn't matter here. The presence of a radioactive material may favor more of death state than alive, so that the superposition sways towards the other end. Then the question is, what is the action of opening? The action of opening collapses the state into one, either death or life and not the superposition of the two. Does the action of opeing the box result in the happenned ...
