Recent mean temperature trends in Pakistan and links with teleconnection patterns
Abstract Monthly, seasonal and annual trends in mean temperatures have been analysed in this study using data from 37 weather stations from the Pakistan Meteorological Department with records from 1952 to 2009. Statistical tests including Sen's slope and Mann‐Kendall were applied to each of the...
