ABSTRACT

Extreme weather events wreak havoc on transportation infrastructure and operations. The consequences of climate change on the transportation sector will vary by mode and region. The impacts on roadways and airports in Imo State, Nigeria, are examined in this study. Between 1999 and 2019, the Nigerian Meteorological Department collected monthly rainfall and monthly air temperature data (minimum and maximum) at the Owerri synoptic station and converted them to an annual average (tables 1 and 2). According to the data analyzed in this study, rainfall and temperature are critical climate variables. This study covers a 20-year climatic history, which allows for a more accurate assessment of climate fluctuation and change in the studied area. Each year's total rainfall was calculated, as well as the average rainfall for the year. The average temperature for each year, on the other hand, was calculated using the same time period as the total minimum and maximum temperatures (table 1 and 2). For the climatic period, the state's mean annual rainfall and temperature data were used to create rainfall and temperature charts (see figures. 3 and 4), which were then used to study the state's rainfall and temperature patterns and patterns of change. However,this study determined that the fluctuations in temperature regimes and variations in rainfall across the state during the study period indicated some evidence of variability and change in the area's climate system, as demonstrated by the observed effects of observed shifts in climatic parameters on the environment and, in particular, transportation.
