Without forests to pump moisture around the planet, would the continents turn to desert? A new theory suggests they might.

The question of how to assess trends in rainfall data is very relevant to that of climate change. A short review of prior work revealed that there was little consensus on the methodology to be adopted. Many methods had been tried and abandoned.

Predicted or confronting you out of the blues, bad weather can give anybody the jitters, especially when each of your business moves, right from the stage of planning to that of execution, will have to be weighed against the vagaries of weather and climatic changes. Not surprisingly, demand for intelligent, location specific weather data and reports has been on the rise.

Urbanization has a dynamic relationship with the physical environment. Urban and rural environments differ substantially in their microclimate. These climatic differences are primarily caused by the alteration on the surface of earth by human constructions and the release of artificially created energy into the environment. Inadvertent climate changes induced by urbanization are well documented.

Analysis of daily rainfall data over India during the period 1951

Total atmospheric moisture content present in the atmosphere is less than 1% of total atmospheric composition. The atmospheric moisture variability accounts for nearly 10% variation in global hydrological cycle. The atmospheric moisture variability occurs in the form of cloud cover and hence in to the precipitation.

Each year, on 23 March, the World Meteorological Organization, its 188 members and the worldwide meteorological community celebrate World Meteorological Day around a chosen theme. This day commemorates the entry into force, on that date in 1950, of the WMO Convention creating the Organization. Subsequently, in 1951, WMO was designated a specialized agency of the United Nations System.

Net primary production (NPP) in the Yellow River Basin, China, during 1982-1999 was estimated with the CASA model using satellite data. The yearly NPP (NPPt) tended to increase during 1982-1999 throughout the Yellow River Basin. A large mean annual NPP for each grid cell was indicated in both the upper and lower reaches, and a low value was indicated in the middle reaches.

How strong a part does water vapor play in global warming?
