This thesis revisited a previous topic on how the downstream and/or large-scale midlatitude response to a recurving TC potentially depends on the strength and/or location of the TC. This study differs from what Brannan and Chagnon (2020)...
A simple one-dimensional seasonal atmosphere-ocean energy balance model is used to study the seasonal and latitudinal response of the model climate to a doubling of the CO2 concentration. A new climate feedback analysis method, ...
The warm core structure of a tropical cyclone (TC) has been previously analyzed through aircraft observations, dropsondes, satellite-borne Advanced Microwave Sounding Unit (AMSU) data, and numerical simulations. It has been shown that...
Climate feedback mechanisms are known to substantially affect the surface temperature response to an external forcing. This study aims to advance our physical and quantitative understanding of forcing and feedback contributions to the...
The 10โ20-day mode of surface winds is examined in the Indian Ocean, with special reference to the Arabian Sea, the Bay of Bengal, and the equatorial Indian Ocean during a strong (1994), weak (2002), and normal (1995) Indian summer...
The geostationary satellite television (TV) signals that are reflected off the ocean surfaces could enter the AMSR-E antenna, resulting in RFI (Radio Frequency Interference) contamination in AMSR-E 10.65 and 18.7 GHz channels. If not...
The measurements from Microwave Sounding Unit (MSU) and Advanced Microwave Sounding Unit-A (AMSU-A) have been extensively used for atmospheric temperature trend study during last several decades. The existences of inter-sensor biases and...
Satellite and ground-based instrumentation, such as radar, lidar and radiometers, have the capability of remotely detecting water, graupel, ice and snow particles in the atmosphere. The detection and characterization of liquid water in...
Initializing Coupled General Circulation Models (CGCMs) for routine seasonal ENSO prediction is currently an onerous task. This is one of the main reasons on why the CGCMs participating in the Coupled Model Intercomparison Project 5 ...
Different phases of precipitation would bring different hydrological impacts. For example, rainfall would become streamflow and increase surface runoffs, while snow would accumulate and increase surface albedo, acting as a crucial driver...
Using data from the National Hurricane Center's (NHC's) Best Track archive, it is found that there are local minima and maxima of occurrence of tropical cyclone (TC) activity in the southwest North Atlantic basin where sea-surface...
The statistical relationship between Rossby-wave breaking and extreme cold air outbreaks (CAO) is investigated for East Asia. Two typical life cycles of upper-level Rossby waves during these CAOs are identified. The extreme CAOs are...
The hyper-spectral Cross-track Infrared Sounder (CrIS) on board Suomi National Polar-orbiting Partnership (NPP) supports a continuing advance in numerical weather prediction (NWP) for improved short- to medium-range weather forecast...
As reported by the University of Central Florida (UCF), Florida nearly leads the nation in fatal vehicle crashes due to fog and smoke conditions. Between 2002 and 2009, 299 deaths were due to vehicle crashes related to fog and smoke...
Clouds play an important role in the earth's energy budget, and changes in their properties can remarkably impact the amount of warming in response to greenhouse gas increases. In this study, we applied the Coupled Feedback Response...
The diurnal variations from a high-resolution regional climate model (Regional Spectral Model; RSM) are analyzed from 6 independent decade long integrations using lateral boundary forcing data separately from the National Centers for...
Earth's atmosphere-ocean system is distinguished by its variability over a wide range of time scales. The non-linear interactions between these time scales are complex and are further complicated by the large number of subsystems and...
High frequency microwave instruments are increasingly used to observe ice clouds and snow. These instruments are significantly more sensitive than conventional precipitation radar. This is ideal for analyzing ice-bearing clouds, for ice...
Extreme climate events may be defined as atmospheric or oceanic phenomena that occupy the tails of a dataset's probability density function (PDF), where the magnitude of the event is large, but the probability of occurrence is rare....
TC structures consisting of eye, eyewall and rainband can be clearly resolved by Microwave Humidity Sounder (MHS) window channels. High brightness temperatures are found in cloud-free hurricane eye and cloud streaks, and low brightness...
This study analyzes projections of summer precipitation over the Southeastern United States under the A2 climate scenario using the Community Climate System Model Version3 (CCSM3), and the Regional Spectral Model (RSM) forced with CCSM3...
In the United States, tropical cyclones (TCs) were the leading cause of natural disaster-related fatalities and Consumer Price Index (CPI)-adjusted costs averaged over the years 1980-2017. Accurately assessing TC-induced extreme winds is...
This study examines the fidelity of the ENSO simulation in two coupled model integrations and compares this with available global ocean data assimilation. The two models are CAM-HYCOM coupled model developed by the HYCOM Consortium and...
Ocean vector winds measured by the SeaWinds scatterometer onboard the QuikSCAT satellite can be validated with in situ data. Ideally the comparison in situ data would be collocated in both time and space to the satellite overpass;...
The atmosphere and the ocean interact through air-sea heat and momentum fluxes. These fluxes are critical in ocean, atmosphere, and coupled modeling across a broad range of spatial and temporal scales, from large-scale global modeling to...
Extreme events are phenomena which occupy the tail-end of a distributions PDF. While atmospheric phenomena are decidedly non-Gaussian, the exact shape of these tails of a distribution are relatively unknown. From stochastic theory, it is...
Ice clouds are crucial to the Earth's radiation balance. They cool the Earth-atmosphere system by reflecting solar radiation back to space and warm it by blocking outgoing thermal radiation. However, there is a lack of an observation...
The 8.2ka Event, a prominent climate anomaly that occurred approximately 8, 200 years before present (yr BP), has been the subject of extensive research due to its potential implications for understanding past and future climate...
The phase of precipitation, i.e., solid (snow) or liquid (rain), is a crucial property in weather forecast, satellite precipitation retrievals, and modeling. The shift of precipitation phase from solid to liquid will alter surface energy...
