GOM will have to be watched next week

Sun, 6 Sep 2009 23:28:00 GMT

Bonsoir everyone It looks like we will have to monitor the GOM closely during the latter part of next week, as a potent longwave trough traverses across the Midwest. The trough is expected to split and slightly troughing in southward, thus kindling upper level anticyclogenesis across the area. The anticyclone will form due to positive vorticity advection at the eastern axis of the longwave trough. Like fluids, air has a tendency to rotate at its own axis, and typic...

Meteorology 101 Diurnal Phases explained!!!! in video

Thu, 3 Sep 2009 23:14:00 GMT

--Water has a higher specific heat capacity than land and air. In other words, it takes more heat to raise the temperature of water by one degree. Thus, water takes more time to warm and to cool. --Since air has a lower specific heat capacity, it has a higher temperature than water during daytime. This creates a mesoscale capping inversion--meaning, that the temperature rises from lower levels to higher levels (relatively...the inversion stops at about 1000ft).When ...

TROPICAL UPDATE!!!!

Sat, 29 Aug 2009 12:00:00 GMT

Tropical Depression DannyTropical storm Danny has been downgraded into a tropical depression, as it moves northeastward at about 11 MPH. Despite the fact that it has weakened, satellite imagery indicates that intense convection has increased substantially with Danny. What is the cause of the increased convection?--An upper level low that is exiting the SE U.S. is interacting with Danny's convection; the baroclinic zone associated with the upper low is enhancing conv...

Record Low Tropical Cyclone--What is the cause? (analysis)

Wed, 29 Jul 2009 18:57:00 GMT

As most of us know, the tropical Atlantic has been anomalously quiet on tropical cyclone activity. In fact, the whole world has been experiencing these unusual quiet conditions. Some say that the atypically low SSTs are responsible for the record low tropical cyclone number, could that be the case?—No, because the upper level dynamics have a more substantial effect on tropical cyclogenesis than SSTs. A minimal Hurricane only needs sea-surface-temperatures to be 80...

TUTORIAL: What Diurnal Phases: DMAX DMIN

Sat, 18 Jul 2009 13:18:00 GMT

Diurnal maximum and minimum. During the day it is diurnal minimum over water because, the surrounding air has less specific heat capacity than the sea,and thus warms faster, but cools down faster during the night. During the night time, the water is typically warmer than the surrounding air. Now the air near the surface which is in contact with the water warms by conduction, and then begin to rise. The during the day, the warming of the air which is above the water ...
