Recently there has been increased interest within the U.S. Navy in the use of climatology-based products to support the planning and execution of military operations. Climatological databases of atmospheric features that impact electromagnetic (EM) propagation have been developed to provide guidance on weapons and sensor system performance for expected environmental conditions. However, the mar...

We expect a numerical simulation to improve upon our first guess; typically some sort of climatology. If a model is not better than this initial estimate of the ocean state, the model provides no new information and serves no purpose. Very often in coastal regions we are interested in predicting events—episodes when the ocean state differs greatly from the climatology. The ability of a model to...

This study was conducted to evaluate soil fertility status in the eight major agro ecosystems viz., coconut, banana, rubber, paddy, arecanut, nutmeg, pepper and vegetables in Thrissur District, Kerala. For this, a total of 30 panchayats out of 92 were selected representing 6 agro ecological zones in the district. Surface soil samples (0-15 cm) @ one sample/ ha. were collected from dominant agro...

Climatology is a comparatively new science which has been progressing rapidly in recent decades. Essentially, conceptualization of its subject—“climate”—is not yet complete. The concept of climate has been transforming along with the development of climatology. At the beginning of the new century climatology is in front of necessity to extend the sense of the concept of climate as compared to t...

The wind/wave climatology for the Arctic Seas will be developed based on altimeter observations. It will have a major scientific and applied significance as presently there is no reference climatology for this region of the ocean available. The new versions of wave models for the Beaufort and Chukchi Seas will include new physics that is already under development, and the novel physics presentl...
