Figure 1. The observed 2011 June-August (JJA) averaged surface temperature departures (°C, top), the time series of JJA Texas surface temperature departures (°C, bottom, left), and the probability distribution functions of the JJA Texas surface temperatures for two sub-periods of the historical record: 1895-1954 (blue curve), and 1955-2010 (red curve). The observed 2011 JJA Texas surface temperature shown in gray tick mark. Data source is the NCDC U.S. Climate Divisions, and departures are relative to 1981-2010 means. The PDFs are non-parametric curves constructed using the R software program which utilizes a kernal density estimation and a Guassian smoother.
