Large-Scale Ocean Circulation

The past 30 years have witnessed a rapid evolution of circulation theory. Much of the progress can be attributed to the intuition and physical balance that have emerged from the use of simple models that isolate important processes. Major contributions along these lines were made by Stommel, Welander, and others. An excellent presentation of the ideas together with a number of significant advan...

Large Scale Acquisition of Paraphrases for Learning Surface Patterns

Paraphrases have proved to be useful in many applications, including Machine Translation, Question Answering, Summarization, and Information Retrieval. Paraphrase acquisition methods that use a single monolingual corpus often produce only syntactic paraphrases. We present a method for obtaining surface paraphrases, using a 150GB (25 billion words) monolingual corpus. Our method achieves an accu...

Influence of atmospheric circulation patterns on dust transport during Harmattan Period in West Africa

This study has used TOMS AI as well as the reanalysis dataset of thirty-four years (1979-2012) to investigate the influence of atmospheric circulation on dust transport during the Harmattan period in West Africa, using Aerosol Index (AI) data, obtained from various satellite sensors. Changes in Inter-Tropical Discontinuity (ITD), Sea Surface Temperature (SST) over the Gulf of Guinea, and North ...
