1) but a nearly identical pattern is obtained by regressing SST* on the canonical Nino3.4 SST Index (not shown).
#PDO FILE FULL#
The PDO can be compared with the global pattern of SST* associated with ENSO, here defined as the leading EOF of monthly SST* over the full Pacific basin (lower panel of Fig. These impacts are primarily driven by associated variability in the large-scale atmospheric circulation, rather than directly by the PDO SST anomalies themselves. The PDO is correlated with hydro-climate over North America, including precipitation, temperature, snowpack, streamflow and drought (e.g., Gershunov and Barnett, 1998 McCabe and Dettinger, 2002 McCabe et al., 20 Wang et al., 2014 among others). These prolonged intervals of mainly one sign give the PDO its name. Periods of predominantly negative PDO phase include 1905-1925, 13, with periods of predominantly positive PDO phase in between.
#PDO FILE SERIES#
The PDO time series exhibits pronounced decadal-scale variability, clearly discernible even with monthly data. The North Pacific PDO pattern is linked to SST* in other parts of the global ocean, most notably the tropical Pacific where it resembles the ENSO pattern, with positive SST* in the eastern equatorial Pacific surrounded by negative SST* in the subtropical western Pacific of both hemispheres. In its positive phase, the PDO pattern consists of negative SST* in the central and western North Pacific, and positive SST* in the eastern North Pacific (opposite signs obtain for the negative phase). The minimum length of record needed to define the PDO is estimated to be about 50 years (Wen et al., 2014 Newman et al., 2015). The results are robust across different data sets, with small variations prior to 1920 when the data coverage is reduced (Newman et al., 2015).
#PDO FILE PC#
The EOF pattern and normalized PC record are displayed in the top row of Figure 1. The spatial pattern is computed by linearly regressing SST anomalies at each location over the global oceans upon the associated normalized Principal Component (PC) time series. The PDO accounts for 27% of the SST* variance in the HadISST (Rayner et al., 2003) data set during the period 1870–2014. The SST anomalies (denoted SST*) are defined as departures from the climatological annual cycle from which the global mean SST anomaly has been subtracted (as a way of removing any long-term trends that might be associated with externally-forced climate change ). (1997), is the dominant year-round pattern of monthly sea surface temperature (SST) anomalies in the North Pacific obtained via Empirical Orthogonal Function (EOF) analysis. The Pacific Decadal Oscillation (PDO), first defined by Mantua et al. Thus, relatively long data records are needed to define and understand the PDO. The largest distinction between the PDO and ENSO is their timescales: While ENSO is primarily an interannual phenomenon, the PDO is decadal in scale. Overall, the PDO's spatial pattern resembles that of ENSO. A weak mirror image of these anomalies occur across the South Pacific.

The positive phase of the PDO is also associated with positive SST anomalies across the central and eastern tropical Pacific. Positive values of the PDO index correspond with negative SST anomalies in central and western North Pacific (extending eastwards from Japan), and positive SST anomalies in the eastern North Pacific (along the west coast of North America). The SST anomalies are obtained by removing both the climatological annual cycle and the global-mean SST anomaly from the data at each gridpoint. One of the functions not working on util.The Pacific Decadal Oscillation (PDO) is defined by the leading pattern (EOF) of sea surface temperature (SST) anomalies in the North Pacific basin (typically, polewards of 20°N). Also, I am remembering to link the utility page and require it on the add.php, etc files. I've read about include, but it has the same documentation as require. $pdo) are being registered and I get an error. But none of the variables I pass as arguments to the functions (ie. However, I am working on moving several repeated processes into a utility.php page that just contains functions. and I am able to access the database fine. I require this file at the top of my index.php, add.php, edit.php etc. I have a $pdo object which simply contains the database connection to Mysql.

I feel like this is pretty basic, but I cannot get it to work.
