Research Projects

El Niño

This project has involved analysing data from a high resolution global ocean model with the aim of obtaining a better understanding of the oceanic processes involved in the development of El Niños.

So far the main paper resulting from this study is Webb (2018a). There have also been two technical reports. These are Webb (2018b) and Webb (2016). A video of a seminar summarising the study is available on YouTube(★★★?).

Tides and Continental Shelf Resonances

Before becoming involved in the El Niño study I wrote a series of papers on continental shelf resonances which affect the tides and result in the dissipation of large amounts of tidal energy.

The first of these papers was Webb (2012), on the Gulf of Carpentaria, followed by Webb (2013a) on the resonances of the English Channel and the Irish Sea and Webb (2014a) on the resonances of Hudson Bay and Hudson Strait.

The Hudson Bay and Hudson Strait region is of particular interest, first, because it absorbs almost half the energy of the semi-diurnal tide in the North Atlantic and, secondly, because it acts almost like a black hole, absorbing at some frequencies over 90% of the incident tidal energy.

glui

I used the mesa library to generate 3-D pictures for my papers on tidal resonances (Webb 2013a and Webb 2014a). Later when I started a project to study the development of the El Nino in the Pacific Ocean I wanted to show the 3-D oceanic fields varying in time and also to make changes to the program variables on the screen while this was happening. For the latter problem the glui library seemed perfect but I found that it produced segmentation faults. I tracked some of these down and so became involved in the glui project. My changes are in repository glui_old.

More recently the original glui code has been rewritten to ensure that it is more stable. One of my earlier edits, which ordered the files and directories in the filebrowser, was never implemented in the original code. The djwebb/glui repository now includes a version which works with the latest version of glui.

moonlight

This is the 2018 version of the Austin et al. moonlight programme:

Austin, R.H., Phillips, B.F. and Webb, D.J. (1976) A method for calculation moonlight illuminance at the Earth's surface. J. Appl. Ecol., 13(3), 741-748.

It is included here on GitHub because it is still occasionally used. The original code was written for an early version of Fortran. In version 2.0 (1999) it was been updated to Fortran 90. In version 2.1:
1. The code has been rewritten to accept dates outside the range 1900-1999.
2. The inputfile can be specified on the command line. For example:
./moonlight PhillipIsland.dat
3. Although the code was developed for the period 1990-1999, tests in 2018 indicate that the positions of the Sun and Moon are still correct to within a degree. Tests covering a longer period of time are planned for 2019.

The code has been tested using the GNU gfortran compiler on a linux computer but should compile successfully with other modern fortran compilers on other operating systems.
