  The World Meteorological Organization (WMO) released a Press Bulletin about the new peaks of concentration of greenhouse gasses on the atmosphere.

 The amount of greenhouse gases in the atmosphere reached a new high in
2010 since pre-industrial time and the rate of increase has accelerated,
according to the World Meteorological Organization’s Greenhouse Gas Bulletin.

Delft Library invites you to a free mini-symposium on 9 June 2011, from
13:30 to 17:00 at TU Delft Library, Prometheusplein 1, Delft


data management and proper citation of research data are important
subjects concerning researchers of all scientific disciplines.
International and Dutch experts will present their views on this
important but often neglected subject. A versatile discussion-panel
consisting of experts from different fields will add an extra dimension
to this mini-symposium.

Dear all, 

Wednesday 8 December Christian Jakob from Monash University,  Melbourne, Australia, will visit TUD. He will give a  presentation which is entitled "Sources of Tropical Mid-tropospheric Water Vapour and Its Role in Controlling Deep Convection".

 Where: TU Delft, TNW building, room G
 When: 8 December 2010, 15.30
 After the seminar there will be an opportunity to share a drink with the speaker. You are all kindly invited!

In recent years it has become apparent in numerous studies that the amount of rainfall in tropical regions is strongly non-linearly related to the vertically integrated water vapor content of the atmosphere. This relationship has prompted the development of a number of simple models of the interaction of water vapor and tropical convection. More recently it has been hypothesized that while low- level processes likely control the occurrence of convection, the mount of rainfall, and by association the strength of convection is controlled by the amount of water vapor in the mid-troposphere. This raises the question which processes are primarily responsible for moistening the middle troposphere and hence providing the environment for strong convection. Likely candidates are horizontal or vertical advection, and non- or weakly precipitating convection of limited vertical extent. In this study we use a long-term data set of the large-scale and subgrid-scale state of the atmosphere derived using the standard variational analysis technique developed in the ARM program at the Darwin TWP-site. Using this long-term data set we first show that this location is representative for the earlier findings on the water-vapor rainfall relationship. We then demonstrate the main source of water vapor for the mid-troposphere prior to heavy rainfall is vertical advection by the mean flow, and not as is often postulated, moistening by non-precipitating convection. Our findings are consistent with the notion that heavy rainfall (and hence strong convection) requires significant dynamical “forcing” to occur.

Is this a sign of the Global Warming ??

Here there are some links to check the evolution of a Tropical Storm, called GRACE … developed in the North-Est Atlantic and heading up towards North-West Europe …
