NASA analyzes Tropical Cyclone Damien's water vapor concentration

On July 8 at 4:50 a.m. EDT (0850 UTC) NASA’s Aqua satellite handed in excess of Tropical Cyclone Cristina, positioned in the Jap Pacific Ocean. Aqua identified highest concentrations of drinking water vapor (brown) and coldest cloud best temperatures have been about the centre. Credit history: NASA/NRL

When NASA’s Aqua satellite passed in excess of Tropical Storm Cristina in the Jap Pacific Ocean on July 8, it gathered h2o vapor info that presented data about the intensity of the storm.

NASA’s Aqua satellite handed more than Christina at 4:50 a.m. EDT (0850 UTC) and the Reasonable Resolution Imaging Spectroradiometer or MODIS instrument gathered h2o vapor articles and temperature information and facts. The MODIS impression confirmed highest concentrations of drinking water vapor and coldest cloud best temperatures were being about the middle of circulation. MODIS data also confirmed coldest cloud top temperatures have been as cold as or colder than minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius) in all those storms. Storms with cloud top rated temperatures that cold have the capacity to create large rainfall.

Drinking water vapor analysis of tropical cyclones tells forecasters how significantly potential a storm has to acquire. H2o vapor releases latent heat as it condenses into liquid. That liquid turns into clouds and thunderstorms that make up a tropical cyclone. Temperature is important when striving to have an understanding of how powerful storms can be. The larger the cloud tops, the colder and the much better the storms.

The Nationwide Hurricane Centre pointed out that satellite images display that the convective business of Cristina is steadily improving, even though bands of thunderstorms are developing throughout the northern part of the circulation. The center of Cristina’s circulation was even now underneath the northeastern facet of the major area of convection due to moderate vertical wind shear, but that wind shear appears to be diminishing.

On July 8 at 11 a.m. EDT (1500 UTC), the heart of Tropical Storm Cristina was located in close proximity to latitude 14.6 levels north and longitude 106.9 degrees west. That is about 350 miles (560 km) south-southwest of Manzanillo, Mexico.

Cristina is moving towards the northwest in the vicinity of 12 mph (19 kph). A switch to the west-northwest is expected by tonight, and that movement is envisioned to go on for the next couple of days. On the forecast keep track of, the cyclone will continue to be nicely offshore the coastline of Mexico. The approximated minimum central tension is 998 millibars.

Highest sustained winds are close to 60 mph (95 kph) with better gusts. Gradual strengthening is envisioned above the upcoming pair of times, and Cristina is forecast to turn out to be a hurricane on Thursday.

Countrywide Hurricane Middle forecaster Andrew Latto famous, “The decreasing shear in excess of Cristina merged with warm sea surface temperatures and a moist air mass really should make it possible for the cyclone to intensify over the future pair of times.”

NASA’s Aqua satellite is one particular in a fleet of NASA satellites that supply details for hurricane investigation.

Tropical cyclones/hurricanes are the most powerful weather conditions situations on Earth. NASA’s know-how in area and scientific exploration contributes to important expert services presented to the American individuals by other federal businesses, these as hurricane weather conditions forecasting.
