Yes, good videos, thank you.

Hello dear Sam, I will tell you the titles of the 13 chapters of the book. 1. Introduction 2. Basic Conservation Laws 3. Elementary Applications of the Basic Equations 4. Circulation and Vorticity 5. The Planetary Boundary Layer 6. Synoptic-Scale Motions I: Quasi-geostrophic Analysis 7. Atmospheric Oscillations: Linear Perturbation Theory 8. Synoptic-Scale Motions II: Baroclinic Instability 9. Mesoscale Circulations 10. The General Circulation 11. Tropical Dynamics 12. Middle Atmosphere Dynamics 13. Numerical Modeling and Prediction If someone wants the book and the solutions, just send me a pm. I think, this book is for beginners, but a good level in advanced mathematics and physics is required. And Dynamic Meteorology from wikipedia: Dynamic meteorology Dynamic meteorology generally focuses on the fluid dynamics of the atmosphere. The idea of air parcel is used to define the smallest element of the atmosphere, while ignoring the discrete molecular and chemical nature of the atmosphere. An air parcel is defined as a point in the fluid continuum of the atmosphere. The fundamental laws of fluid dynamics, thermodynamics, and motion are used to study the atmosphere. The physical quantities that characterize the state of the atmosphere are temperature, density, pressure, etc. These variables have unique values in the continuum.[58] http://en.wikipedia.org/wiki/Meteorology#Dynamic_meteorology

I am talking about the book: An introduction to Dynamic Meteorology (4th edition). Author James R. Holton. Are there members of the forum who want to discuss about the theory, problems and matlab exercises of this book? I am available. I have started reading this book. Anyway, I will try to solve all the problems and the matlab exercises and I will upload the results here (maybe in a pdf). I hope that the rules of the forum allow me.

0% chance of tropical cyclone formation the next 48 hours... lol I cannot change the title...

At night? Yes it is... I think so.

This will be a power typhoon... http://tropic.ssec.wisc.edu/real-time/storm.php?&basin=westpac&sname=04W&zoom=4&img=1&vars=11111000000000000000&loop=0

This is the last time for 105 years Venus will be in the straight line, between Earth and Sun.

Ok, I understand and thank you. I thought it will be similar to Eclipse, but now I am disappointed. Hahahahaha... Ok, I will follow the news organizations and NASA. I created a page on facebook about Transit of Venus 2012 in Greek language, but I will also write in English. If someone wants, please like it: http://www.facebook....iAphroditis2012

Will it be visible with our eyes? Will we see a black spot in sun? Is it necessary to use eyeglasses? If so, can you suggest me a good and cheap brand of eyeglasses for this purpose? Do you have a good idea in your mind? Thank you.

What about 90% humidity in your region? Is it raining? I think you need more temperature there. For example 28C 90% humidity implies heat index 34 C.

Ok this is very good. Thank you. So now, the real feel of the temperature out of my house is 19 degrees C.

94 L in Caribbean. 40% (now) Chance of hurricane formation the next 48 hours: http://www.nhc.noaa.gov/gtwo_atl.shtml

What about records? Has this (fact) happened again in the past? In records, we have only cat 2 hurricanes in May in the East Pacific?

How do I calculate the real feel of temperature if I know the temperature out of my house, the external humidity and the air pressure? Is there a mathematical formula? For example now the temperature out of my house is 19.5 degrees C, the external humidity 61% and the air pressure 990 mb. So, how is the real feel of temperature out of my house? Thank you.

NOAA NWS National Hurricane Center Hurricane Bud continues to strengthen. As of early this afternoon, top sustained winds had reached 110 mph, a strong Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some additional strengthening is possible today, with weakening expected to begin tonight and continue into Saturday. Bud is centered about 250 miles southwest of Manzanillo, Mexico, moving northeast. A Tropical Storm Warning and a Hurricane Watch continues along the Pacific coast from Punto San Telmo westward to Cabo Corrientes. A Hurricane Warning may be necessary later today for a portion of the southwest Mexico coastline. For the latest on this hurricane, including watches, warnings and graphics, go to the NHC website at www.hurricanes.gov
