Weather It Is (Still Fall...)

Oct-14-2017 20:14

Good Evening:

Peoples wardrobes are changing over and the weather is to blame.

We even had our first rain last Monday (October 9th). I measured 0.12 inches (or about 3 mm of rain).  Since then, the weather has been on the chilly side with temperatures in the mid teens and highs in the low to mid 20s (except in the desert areas, which were closer to 30 C).

Who we are


Dr. Barry Lynn - CEO

Dr. Lynn received his Ph.D in meteorology from Rutgers University. He is currently a research scientist at the Hebrew University in Jerusalem, and in the past served as a research scientist at Columbia University, Carnegie Mellon, and at NASA. He has published nearly thirty research articles in respected journals. His areas of research include numerical modeling of severe storms and lightning, the impact of greenhouse gases on climate and the effect of aerosols on precipitation and hurricane development.

Professor Richard Lynn - CFO

Dr. Richard Lynn worked as a financial analyst and portfolio manager at the Atlantic Richfield Company. He has a B.A. from Columbia College, an MBA from Harvard Business School and a Ph.D. in Finance from Columbia University. He was an Associate Professor of Finance at Pace University until his retirement.

Upcoming changes are planned to the Weather It Is site.

First, the forecast model that underlies all of our forecasts should be updated in September. This will bring on-line improved forecast algorithms, including improvements in calculating the movement of storm systems from one location to another , and improvements in the physical packages that we use to determine temperatures, humidity, wind, and precipitation.

Second. we are in the process of installing a lightning network. The lightning network will be used to power mobile applications that will provide timely and important weather warnings to private industries and the public. When severe storms approach our area, you'll know, and be able to take protective action before the storm hits.

Third, we're continuing to make improvements to the site. So, look for greater flexibility on the pages and clear presentations.

Please write us if you have comments or suggestions.
