Abstract

It is high time now to recognize the alarming signals of climate change since many parts of the globe have already started witnessing its fury. The knowledge in the process of climate change may help communities to fight against it. Hoping that climate change is leaving its footprint in the meteorological parameters, the authors intend to study some of the following: cloud liquid water (CLW), precipitation water (PW), and latent heat (LH) from the Earth’s surface up to a height of 18 km above; the rainfall and temperature (T) over a few locations in India, namely Vishakhapatnam, Mumbai, Chennai, Kakdwip, Trivandrum, Machilipatnam, Panjim, Puri, Karaikal, and Mangalore. In addition to this, the authors have made an effort in particular to explain the peaks and troughs of rainfall time series. For this purpose, in addition to the above mentioned locations, a few more locations outside India, namely Papua New Guinea, Costa Rica, Mediterranean Sea, Panama, East China Sea, South China Sea, Taiwan, Indian Ocean, Gulf of Mexico, Pacific Ocean, and Mozambique, have been included in the study. The rainfall, CLW, PW, and LH values are obtained from the data product 2A12 of the Tropical Microwave Imager (TMI) onboard the Tropical Rainfall Measuring Mission (TRMM) satellite for the period 1999–2008. The surface temperature values are obtained from the National Oceanic and Atmospheric Administration (NOAA). The monthly and yearly variations in CLW, PW, and LH; their variations in the southwest (SW) and the northeast (NE) monsoon have been studied. An attempt has been made to find out whether the change in these quantities has any effects on the surface temperature and rainfall. The authors intend to find out whether a similar trend is found out in the variations in rainfall, surface temperature, and these quantities. An effort is made to discover the impact of these quantities on the number of occurrence and intensity of cyclones and storm surges. Further, the variations of CLW, PW, LH, and rainfall with the latitude have been investigated.
