Regional Climate Scientist
Portrait Daniel Argüeso


I am currently a postdoc researcher at the Department of Atmospheric Sciences in the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawai'i at Mānoa, Honolulu, HI, United States.

In January 2017, I was a awarded by the European Commission with a Marie Sklodowska-Curie Actions Individual Fellowship to determine our ability to simulate realistic precipitation in the Maritime Continent. This project will start in October 2017 at University of Balearic Islands, in Palma, Majorca (Spain).

In the last few years I have been studying the regional implications of global warming and how climate change will manifest at scales that have a direct impact on humans and the environment. I have been involved in projects such as PROCLIAN and NARCliM aimed at generating high-resolution climate change projections to ascertain the climate change repercussions for various regions. Specifically, these project have addressed potential changes in temperature and precipitation, the regional circulation and the frequency and intensity of extreme events. More recently, my research has also focused on the effects of urban areas on variables such as temperature, humidity, wind and precipitation, with emphasis on their role under climate change conditions. I am also interested in convection-permitting climate modelling and its potential to improve the way we simulate processes in the atmosphere, particularly those related to rainfall.

At this moment, I am working on the generation of a wind gridded dataset over O'ahu, Hawai'i using very high-resolution regional climate models to assist in the design and location of future wind farms both on the island and offshore.

High temperatures by the end of the Century will result in longer, more frequent and more intense heatwaves. Mean temperature will increase producing a shift in the distribution, but in some cases extreme temperature will increase even more, modifying the shape of the distribution (i.e. temperature variability). Previous studies attributed a key role in defining future heatwaves to both changes (mean and variability). However, we showed that it is essentially the mean seasonal warming that drives heatwave changes. That is, estimates of mean summer warming added to present climate temperatures provide very accurate information on future climate heatwaves. In most cases, 95% of heatwave changes magnitude can be obtained from seasonal warming alone, while variability changes contribute to less than 5%. That 5% is still important, but perhaps not as much as we previously thought.

Did you know that cities can have a deep impact on local precipitation? In our recent paper in Climate Dynamics we show that urban areas in the Maritime Continent can substantially change precipitation rates locally. This is because rainfall in the region is mostly convective and precipitating systems have scales comparable to the size of cities. The surrounding warm shallow ocean and the complex topography are key factors in shaping the archipelago rainfall, which in most cases has a strong diurnal cycle. Our study shows that dry warmer urban areas interact with local circulation enhancing convection through moisture convergence and increase both the frequency and the intensity of precipitation.

We just got published in PLOS ONE our study on the effects of city expansion and climate change on heat stress in Sydney. In agreement with previous research, we found that humidity and temperature changes will contribute to an increase in heat stress in rural areas. However, these two variables will contribute in opposite directions to changes in heat stress due to urban development, because cities tend to increase temperature but reduce humidity. Our results from very high resolution climate simulations indicate that during the night, temperature increases dominate the heat stress changes. On the other hand, daytime changes in temperature and humidity will almost compensate to produce little to no changes in heat stress. This study highlights the need to estimate changes in variables beyond temperature to address the exposure of population to heat stress conditions under future climate change and urbanisation scenarios. It also lays the groundwork for future research on how to better design cities to reduce the impact of on urban population using climate models that generate climate projections incorporating the effect of the built environment.
