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.

Building Resilience in the Face of Climate Change: The Limitations of Adaptation

Climate change is an undeniable reality, and its impacts are already being felt across the globe. However, many parts of the world, particularly developing regions like sub-Saharan Africa, are ill-prepared to adapt to these changes. This lack of preparedness stems from several interconnected factors: Limited access to climate predictions: Many regions in sub-Saharan Africa lack access to reliable and accurate climate predictions, making it difficult for communities to anticipate and plan for future climate-related events. Inadequate adaptation technologies: Even when climate predictions are available, communities may not have access to the necessary technologies and resources to implement effective adaptation measures. This can be particularly challenging in regions with limited infrastructure and economic resources. Dependency on external aid: Many developing countries rely heavily on international aid to support climate adaptation efforts. However, this can create a dependency on...

Urban surface parameterizations, uncertainties and challenges

My recent review paper "Review of urban surface parameterizations for numerical climate models"( https://www.sciencedirect.com/science/article/pii/S2212095517300858 ) presents the historical development of urban climate models, uncertainties and challenges  in obtaining representative urban weather and climate information. There are wide scale urban weather/climate models and the level of detail and complexity required for a particular study is oftentimes a challenge for the climate modeling communities. Weather/climate models are required for different purposes, such as understanding the teleconnections between different scale weather/climate phenomena, for weather forecasting and climate projections, and for policy purposes. Therefore, improving the performance of climate models is one of the top priorities in the climate modeling communities. On the other hand, obtaining accurate initial and boundary information is challenging. Observations data of high spatial density ...

Notes on spectral nudging urban climate models - Nudging is wrong, do not do it

Debate erupted about spectrally nudging regional climate models during summer 2016 training on regional climate modeling at National Center for Atmospheric Research (NCAR). The debate was whether nudging is valid for regional climate models. Because of the interest of many participants who were PhDs and postdocs from all over the world, special session was assigned for extended discussion. I was new to the nudging concepts at the time, but thought that it is interesting, especially whether nudging is useful for downscaling reanalysis and GCMs incorporating urban canopy models. I dropped my ear and followed the discussion. Based on the ideas raised from the organizers and participants, I also forwarded some questions of relevance for the urban climate modeling. As an extended discussion during the afternoon, many questions were raised: If a regional climate model is spectrally nudged, doesn't it lose its added value as a regional climate model because nudging forces the model t...
