¿Cómo afecta nuestra rutina la investigación sobre el clima y el tiempo?

Have you ever been stopped to think how climate research and weather affect our daily lives? “This science has a direct impact on the daily lives of us all, from small decisions such as whether to wear a coat or an umbrella or not, until the government analyzes whether deposits dams hydroelectric plants will have enough water for energy production, “says Caio Coelho, a Brazilian researcher at the Center forecast Weather and Climate Studies (CPTEC), National Institute for Space Research (INPE).

“Another example of the usefulness of seasonal climate forecasting is planning trips. If we know for example, that next month will be drier or wetter than normal, we can decide most appropriate destinations for our profile, minimizing potential discomfort “added the specialist.

CPTEC is responsible for weather forecasts and seasonal climate forecasts to environmental (air quality) and to make projections of climate change scenarios in Brazil. And to display the data summarized in the weather forecast, indicating whether we will have sunshine, rain or cloudy weather, there is a long way to go.

“This science has a direct impact on the daily lives of us all”

“Daily weather data from various regions of the world are used to initialize global numerical model of CPTEC and generate the weather forecast for the coming days. Regional models are also included in the supercomputer Tupã to provide a greater level of detail for the weather forecast. forecasters evaluate the forecasts produced by numerical models, add knowledge of local and regional weather conditions, then produce the weather forecast for next days in Brazil, “Caio said.

It is a work in progress. “We maintain an IT infrastructure running 24/7,” says Eugenio Almada, researcher and specialist in Information Technology CPTEC. It also explains that in addition to being connected to the RNP, the CPTEC has a “strong interaction with the organization.” “In my time, networks were low speed were not reliable and were unavailable for a few days. With the connection to the academic network, we improve this scenario and the speed of data transfer. We must no longer leave the CPTEC to interact with colleagues and can supply weather data growing rapidly, with the certainty that the other party will receive the information, “he says.

Thanks to the high-speed connection is facilitated interaction with colleagues and today can communicate with researchers from other countries and even the general public. “Just to cite a recent example of international collaboration due to the water crisis produced in the southeastern region of Brazil, particularly in the metropolitan region of São Paulo, which attracted international scientific interest, researchers from Europe, USA and Australia they contacted CPTEC researchers to develop a study to identify potential human contributions capable of changing climate risk in drought situations as those seen in 2014 and 2015.

Through analysis of observational data and application of global climate models, the researchers found no evidence of modification of climate risk of drought due to human activities responsible for the emission of gases that cause the greenhouse effect, and concluded that the increasing population and water consumption were most likely primarily responsible for water shortages in São Paulo during this period, “says Caio.

“An interesting aspect of this study was the use of a voluntary network of personal computers called to perform thousands of climate simulations, which allows the public interested in this subject contribute to research , ” adds the researcher.

Thus, the Internet connection through the academic network plays an important role in sending and receiving a large volume of data. “The connection to the Ipê network has many benefits, both from a scientific point of view with the rapid exchange of information for the advancement of science, and from the practical point of view to help the government with providing weather information for the development of public policies, “he said Caio Coelho.
