What is it about?

Temperature change was investigated by observation and numerical calculation in poor-ventilation site. The poor-ventilation, which could be caused by tree-growth and building a fence, in surface observation site increases daytime air temperature and decreases nocturnal temperature.

Why is it important?

The poor ventilation should be one of causes of urban heat island. However, very small number of paper showed the poor ventilation in urban climatology.


This topic is not commonly discussed in meteorology, but it surely have great influence on the climate change monitoring.
