Research On The Relationship Between Global Climate Change And Aircraft Route Fuel Consumption

The impact of hourly fuel consumption on the aircraft's battery life and long-distance speed is very important.The paper uses the global atmospheric monthly reanalysis data and monthly atmospheric remote correlation index data provided by NCEP/DOE from 1979 to 2018,using correlation analysis,linear regression,synthetic analysis and other methods,taking the B787-8 aircraft as an example,From a climatological perspective,studied the spatial distribution characteristics of its hourly fuel consumption at different cruising altitudes in the northern hemisphere,and analyzed and studied three regions with large interannual variability of hourly fuel consumption in the northern hemisphere,and the following conclusions are obtained:(1)In terms of climatology,the hourly fuel consumption of the B787-8 aircraft has the characteristics of being distributed around the poles in space,and has obvious regional characteristics.At the cruise altitude of 250 hPa,the three small areas of hourly fuel consumption are located near the high latitudes of the Western Canada's Mackenzie Mountains,Greenland,and the Stanov Mountains in northern Russia.At a cruise altitude of 300 hPa,the spatial distribution of hourly fuel consumption of the B787-8 aircraft is roughly the same as that of 250 hPa.The 200 hPa cruise altitude hourly fuel consumption spatial distribution is different from the 250 hPa cruise altitude.The biggest difference is mainly located in the Arctic region.The former Arctic small-value area changed to a large value area near the Queen Elizabeth Islands in northern Canada.(2)Arctic region(70°N-90° N),Pacific region(10°N-30°N,127°W-168°W)and eastern China(28°N-40°N,100°E-120°E)is a region where the inter-annual variability of hourly fuel consumption of the B787-8 aircraft in the northern hemisphere is relatively large.(3)Arctic Oscillation AO,ENSO,and East Atlantic / Western Russia Model Remote Correlation(EAWR)and aircraft hourly fuel consumption in the Arctic,Pacific,and eastern China respectively have significant interannual time scales.Relationship,and this correlation is unstable in different seasons.AO and Arctic Hourly Fuel Consumption are negatively correlated in winter,but changed to positive correlation in summer;East Atlantic / Western Russia Model Remote Correlation(EAWR)and Summer Hourly Fuel Consumption in Eastern China It is a significant negative correlation,but the correlation coefficient in other seasons is not obvious;ENSO and the hourly fuel consumption in the Pacific region show a positive correlation in all seasons,with the largest positive correlation coefficient in winter and the smallest positive correlation coefficient in summer.(4)The Arctic Oscillation AO and the East Atlantic/Western Russia Model Teleconnection Model(EAWR)in the middle and lower layers of the troposphere first pass the anomalous distribution of potential height fields and temperature fields at the same height,and then the potential height and The temperature field is compatible with the lower and middle troposphere,which affects the abnormal distribution of fuel consumption at different cruise altitudes.The sea temperature anomaly in Nino3.4 area,through the interaction between sea and air,the strong sea surface temperature affects the change of the tropospheric temperature field,which makes the troposphere's upper and lower troposphere temperatures warmer and the upper troposphere-stratosphere temperature It became colder,which in turn affected the hourly fuel consumption of the B787-8 aircraft.
