Numerical simulation of urban heat island intensity under urban–suburban surface and reference site in Kolkata, India

Urban heat island intensity (UHII) in Kolkata has been assessed using simplified numerical model for vertical temperature measurement in tropical monsoon summer month (June, 2015) during pre-onset of monsoon season. The data of 25 field observation sites show that the surface temperature curves are likely to mathematical trapeziums, and surface temperatures are related to...

Subject choice in educational data sets by using principal component and procrustes analysis

Principal component analysis (PCA) is a dimension-reducing technique that replaces subjects in a multivariate data set by a smaller number of derived subjects. Dimension reduction is often undertaken to help in describing the data set, but as each principal component usually involves all the original subjects, interpretation of a PCA result can still be difficult. One way to...

Spatial modeling of urban sprawl around Greater Bhubaneswar city, India

, Presidency University , Kolkata , India 1 & Ansar Khan In developing countries, where urbanization rates are high, urban sprawl is a significant contributor of the land use change. However, characterizing

Momentum flux and energy flux associated with internal gravity waves excited by the Assam-Burma hills in India

In this paper an attempt has been made to parameterize the momentum flux and energy flux associated with internal gravity waves excited by the Assam-Burma hills in India in a baroclinic mean flow. For that a linear dynamical model for air flow across a three-dimensional meso-scale elliptical barrier has been used. In the present study ABH has been approximated by two 3-D...
